AMD Radeon HD 7970でbitcoinのマイニング(仮想通貨の発掘) テクノロジーのはざま

Back to the Future: 2014 Bitcoin increase, market Crash, and GPUs flood the market.

Image a world, where Bitcoin hits a new ATH of 1,000 USD! A new coin emerged, Litecoin. Using a new Algorithm called SCRYPT which makes GPU mining profitable and a thing again!
The story starts in January 2014. AMD Just released it's newest GPU, the R9 290X in late Oct. this thing a monster of a GPU, extremely powerful! A GPU mining crazy has just hit the internet and waves of Tech people are making mining farms to mine Crypto. AMD GPU's are priced at premiums with 290's/290x's OOS or for sale upwards of $700, $200 over MSRP. Everyone is gulping up used AMD GPUs. Ebay is awash with GPUs selling over MRSP even used ones!
I was there, I started out mining Litecoin to Litecoinpool.org, I had 3 Rigs I slapped together in crate boxes. Mixature of 7970/7950/7850's and a single a 4 GPU R9 290x rig (over 1400w!!!) using AMD AM3+ Motherboards and CPU's running Windows 8. I even near the end had a 750ti Rig, the new Maxwell, efficiently mining SRCYPT. I'm glad i lived in WA at the time The electric bill wasn't bad at all maybe 200-300 a month. I lived in Ellensburg getting that sweet Wind farm Electric rate. I Remember this time as I struggling to learn mining, overclockings for mining, and rig stability. In the short period I did this February 2014 to May of 2014 I made 48 Litecoins. This was a fun period for me because I loved messing with the hardware and GPUs even made decent profits from selling used hardware because it became such a premium then. In the end I quit mining and sold all my hard around May/June. Then moved back to CA to live with my mom to help support her after she lost her job and couldn't find work. I sold off my entire small operation. In the end the Market crashed, MT GOX was hacked millions of Bitcoin lost, and SCRYPT ASICs were released. I stopped paying much attention to the crypto-sphere and just HODLed the small Bitcoin that I had traded from the Litecoin I earned. Bitcoin dropped down to $200 by the end of that year.
All in all I just want everyone to take in the fact that this exact, I repeat EXACT, thing has happened before in the long forgotten past of 2014. Yet everyone is making it out like its some crazy big deal? every crypto is still at high comparing to previous years, GPUs have declined in price because mining has died down, and ASICs are coming out for almost every Algo.
To those of you still mining, keep on my brother! If I had kept mining, or kept on eye on the crypto sphere rather than walking away like most are right now, I could mined Etherum back in the early days of 2015 and now could of been extremely well off. Now, that im in it again and this time with more foresight and readiness. I'm here to stay through this rough times. hopefully to come out to see the otherside. I Only started(again) in june 2017 so I was late for this "gold rush" but mark my words the massive "Gold rush" for crypto has yet to come...

[Discussion] My own personal guide to used hardware alternatives.

Hi there. My name is Jeff. I've been building systems for the better part of 15 years and try my best to contribute here actively. After being involved in this little community for a few years now, I'm noticing a serious lack of discussion about buying used components, and I feel like it's time to shed a little light on the subject for those looking to build on a (seriously) tight budget.
As Linus said in his scrapyard wars video, buying new on $300 isn't practical, and if you posed the challenge to him on a random day, buying used is almost certainly the path he'd choose. As someone who's been "scrapyarding" as a hobby for the better part of 10 years, I figured I'd take some time to share some of what I've learned for the modern audience.
Let's begin with a simple rundown of modern "budget" choices, and I'll tell you what I'd do instead.
CPU
The G3258 and Athlon 860k are the sub-$100 CPUs of choice, and both work just fine. I have built with both in the past, and each carries their own set of advantages.
Used Alternatives: You can go in a couple of directions here; if you happen to have an LGA 1366 motherboard lying around, you can get an i7 920 or better for under $50, and they still hold up reasonably well. Being that LGA 1366 boards are not typically cheap when purchased used, my favourite option is the Phenom II x4 Black Edition series, each of which compare favourably to modern budget options, and will even overclock on some incredibly dated, dirt cheap AM2+ boards. In my experience, eBay prices on these get a little too high for my taste, but I've been able to nab several on Kijiji locally in Toronto for under $50 as well.
GPU
The R7 260x and GTX 750 ti are often cited as budget options for most builders, with the latter serving a very specific role in systems where power draw might be a concern. While there exists no option that can complete with the low consumption of the 750 ti (or even the single 6-pin connector goodness of the 260x), its performance can easily be matched (and exceeded) for less money.
Used Alternatives: The bitcoin mining craze from a few years back led to the Radeon 7950 and 7970 being blacklisted on the used market, and I think the fears about burned-out cards are a little overblown. Here in Toronto, you can easily grab a 7950 for the price of a 260x, but I don't pay anywhere near that for my builds. At most, a Windforce will cost me $125, as where I recently picked up some non-boost edition PowerColor versions for a mere $83 each (bought 3 for $250).
EDIT: Forgot to mention something important - avoid the reference 7950 and 7970. They were employed to a far greater degree in mining rigs because of their rear-only exhaust, and if you see a bunch of them from the same seller listed at once, they're likely old mining cards. Only pick them up if they're incredibly cheap.
Want to go even cheaper? The Radeon 6950 (with the shader unlock, preferably) or even the 6970 will rival the performance of the 260x, and shouldn't cost Canadians more than $50-$60. I personally have 2 in my possession right now, and have gone through at least a dozen in the last 6 months.
In general, one should always avoid Nvidia when buying used, because they are far too popular and overvalued for their performance as they age. I still see GTX 660s selling for $150, which is absolutely absurd.
Motherboards
Motherboards on the used market are weird, and this can largely be attributed to the fact that they're hard to transport and don't handle well over time. As such, people don't really sell boards on their own that often, and you'll likely have more luck finding a combo of some kind (or even a ready-to-go tin-can with no graphics card) for less per part than you will finding a given board on its own.
Used Alternatives: The boards I'd recommend depend entirely on the CPU you've chosen. Being that I'm a fan of the Phenom II x4 series, AM2+ boards are going to be dirt cheap, but DDR2 RAM is actually fucking expensive, so you'd likely be better off going with AM3. I've even seen some used AM3+ boards (The 970 ASRock Extreme3, in particular) for as low as $40, so it wouldn't hurt to look.
On the Intel side, you're actually at a significant disadvantage. Much like Nvidia cards, Intel boards (and CPUs) actually retain their value and don't often come cheap. For me, LGA 1156 is the price/performance sweet spot, granted I can find an i7 8XX to go with it. Even still, they're going to run you a fair bit more than an AMD board, and likely aren't worth it by comparison.
RAM
Ram is ram. DDR2 is pricy as fuck due to an obvious market shortage of the stuff, so the AM2+ board option might not be best by comparison. DDR3 ram, however, is ubiquitous, and I always die a little inside when people building on a "budget" choose to buy new at all. If I'm being honest, I can get DDR3 ram from e-waste recycling companies for as low as $10 per 4GB stick, at 1333MHz, and not once have I ever had a bad stick of the stuff. Even for people going the route of the G3258 (which only supports 1333MHz), this is the clear winner.
Is value RAM ugly as sin? Sure it is. It is just as good as that fancy Ripjaws shit you've got in your current build? You betcha.
Storage
Hard Drives are actually a tricky game, as they are the single most volatile component in any budget build, easily succumbing to wear and tear from age and daily use. As such (and some might find this hard to believe) I actively avoid HDDs when building value systems for people and opt for cheap SSDs instead. As always, check the date on a drive if you're really insistent on buying one, and considering how cheap a WD blue is new, don't pull the trigger on one unless it's for less than $30/TB.
SSDs are obviously (akin to RAM) highly resilient and are nearly guaranteed to work when purchased used. The average SSD pulled from an old laptop or an office off-lease desktop, will have no more than 100GB of writes on it, which leaves 99% of its life for you to exploit. While there exists no specific recommendation for which brand to buy, just be sure you're getting a relatively good drive with SATA III capability. 120/128GB variants of these sorts should cost you no more than $50 in my native Canada, and I've even gotten lucky on some larger sizes too. Recently I picked up 4 256GB Samsung 840 Pros for $75 each (I came), just days after I bought a Crucial MX100 of the same size for $85.
Monitors
Monitors are fun to buy, because the recent shifts in display technology have rendered a lot of recent-but-obsolete models nearly valueless. For example, remember when 16:10 was a thing? I actually still like 1680x1050 monitors, but the rest of the world seems to disagree, so I've been able to pick up 23" variants for as little as $40. Being that the slightly lower resolution actually eases the strain on your VRAM a bit, it's a nice fit for a lot of budget cards that might not have a full 2GB available, like some variants of the 6950. 1600x900 monitors are often just as cheap and come with the same inherent benefit of being obsolete despite being almost as good as its bigger 1080p cousin.
Keyboards and Mice
If you're on a budget, we can't even have this discussion. As much as I like mechanical keyboards and high-precision gaming mice, people building used $300 systems aren't going to allot any of their budget buying them. That said, wired USB keyboards and mice are virtually free (search your local goodwill or value village for some), and if you have to pay money, buy a wireless combo for $20 new from some little shit store in a suburb somewhere.
Cases
Cases on their own sell for about half of their original retail price, give or take based on the condition. I normally just get them as a part of a tin-can bundle and make use of them if they aren't too dirty, but when building for someone else, I'd often just prefer to buy a new budget case in the $40 range.
PSUs
I saved this topic for last, because it's by far the most difficult category to master. First off, you really need to do your research and understand how PSUs work before delving into these guys, as the cost associated is almost entirely dependent on how resilient the underlying platform has been proven to be. Generally speaking, reading reviews on JonnyGuru and HardOCP is a great start, but none of them account for units that are several years old.
As a general rule of thumb, I use the EVGA 500W W1 as a reference point, and build my value tree around that. In other words, if a new EVGA 500W (a passable, proven budget unit) is cheaper than a used 500W variant of a better brand, why would I bother buying used? Sure, that 520W Seasonic S12II puts the EVGA to shame in terms of voltage regulation and ripple suppression, but can I really make the same claims of a unit that's 5 years into its life? Wouldn't I just be safer buying new? These are all factors you have to consider.
For me, the threshold lies around 50% in terms of cost savings vs. risk. In other words, if you can find a used quality unit for less than half the price of the cheapest quality unit available at a given time, buy it.
Anyhow I think that covers everything. And as a closing note, remember to be safe. Meet potential sellers (and buyers) in public, well-lit places, and try your best to avoid entering someone's home without some protections in place. Also, the more info you get about the person (address, phone number, etc) the less likely it is that a person will be trying to scam you. People who purposely conceal their identity do so for a reason.
Also, feel free to ask me anything about my own experiences buying and selling used. I've been doing it as a hobby for a long, long time and have sold many value builds to people who can't otherwise afford PCs. I'm happy to impart any wisdom I might've gained over the years.
Edit: CPU Coolers! Forgot those. Air coolers are a safe bet. They're slabs of copper and aluminum with fans strapped to them. Buy with confidence, and seek one out for $10-$15 if you plan to overclock. AIO water cooling is not so safe. Those things are typically only good for 2-3 years, and you have no idea how much longer a pump has before it gives. Budget builders likely aren't water-cooling anyhow, right?
Edit 2: Just to be clear, when I said I'd been doing this for a long time, I should clarify that a) I once owned a game store and sold systems out of there and b) I currently resell systems out of my house to raise money for charity builds. I really don't want people to get the impression I'm trying to sell anything.

A disgruntled opinion/rant regarding Bitcoin/Litecoin/etc. mining and the enthusiast GPU market.

Back in June of 2012, I very eagerly built my rig with a single Radeon 7950 in anticipation of crossfiring it down the road with a 7970. Now that time has come, and in my efforts to procure what I had anticipated to be quite the bargain, I am absolutely flabbergasted by what I discovered.
There's not a decent Radeon 7xxx in sight, and the 7970s that I could find are going for upwards of $400 USD! This is simply unacceptable for a two-year-old card, and even more unacceptable when considering that these very cards were (according to this guide) retailing for $269.99 this past October! That is nearly a 50% price increase in just two months at the very end of the card's life, and just after the universal price drop to all 7xxx units complimenting Nvidias launch of their GTX700s.
I hope I'm not being oblivious/naive here - and please correct me if I am - but I have NEVER seen that happen before with ANY consumer product (that is being replaced by a new revision). Of course I know the economic rules of supply & demand: There are lots of people who want these few cards, so AMD can afford to boost the price on them. However, this is pretty unreasonable considering AMDs focus on the new R9 chips, which are the new supply.
The perpetrator here is the growing trend of Bitcoin mining. The computing power and efficiency of AMDs GCN architecture is extremely good at mining for this "magic internet money." A growing amount of people are noticing this, and thus demand for AMDs chips has blown up like crazy. It's even become a goddamn selling point in advertisements.
I understand that the processing power of these cards can be very well harnessed for coin mining, and that's fine. However, for those of us enthusiasts that enjoy using our video cards to push pixels, I anticipate this trend to continue putting a strain on the market and our wallets.
TL;DR: I'm butthurt about last-gen AMD GPU prices being unreasonably high, and get mad (within reason).
*edit: AMD is not boosting prices, retailers are. Thanks to Shrederrr for clarifying.
**edit: To all the people suggesting that I sell my 7950 on the secondhand market, thanks; that is a good idea. Honestly the solution didn't cross my mind at the time of making this post - I was still reeling from the unbelievable prices and frustrated that I wasn't able to follow my planned upgrade path. This unprecedented Bitcoin/Litecoin phenomenon caught me by surprise and it saddens me somewhat to see these enthusiast GPUs being used in such a menial, greedy fashion. It's like seeing a Ferrari V12 powering a backup generator for a t-shirt factory. Sure it's being put to good use, but it's just...not right.

Not So Brief History of my Radeon HD7950 ASUS Direct CU II

Sexy Beast Pic 1: https://i.imgur.com/dQC90.jpg
Sexy Beast Pic 2: http://www.legitreviews.com/images/reviews/1839/7970-dc2-top.jpg
ASUS HD7950 Direct CU II. This card mined 1.5-3 BTC Bitcoin for me. Started with Bitcoin, then mined Litecoin in the early days of Litecoin GPU mining. Had 2 X ASUS HD7950s running 24/7/365 at the time. Each did about 3 BTC each total, and then switched full time to LTC Litecoin. This card was also used for CS gaming, 3D rendering, real time graphics, some video editing, and yes, yes more mining! Still RUNNING today! AMD FTW!
After some test mining Litecoin for a month, I quickly built 2 more Radeon GPU rigs to mine LTC. Total 3 rigs 12 cards. Blazin! Then in Dec 2013 this setup mined millions of Dogecoin in a few days shortly after launch,... I remember raking in over 300-500K DOGE / day at full throttle. We setup our own Doge Pool, and DOGE miners were chatting on IRC: The Excitement was REAL!
This fun SUCH DOGE WOW time was cut short by a massive ice storm that knocked out the power for a week. So no more DOGE. When I got back online diff was up and production down to 30K per day or less, but DOGE price skyrocketed so I sold DOGE for a good profit.
I remember donating DOGE to send the Jamaican Bobsleigh Team to the 2014 Winter Olympics, and they made it to Sochi! What a time to be alive! I was a DOGE Millionaire by then... Such Card, Much DOGE! WOW!
Shortly after that, around March 2014 the second HD7950 blew some caps and need to be sent to ASUS for service. ASUS promptly replaced the card under 3 year warranty and shipped a replacement in two weeks. Mining frenzy continued with FeatherCoin and PotCoin. DGB Digibyte was the next chapter! ;]
In summer 2015 I decided to part with one of them. Sold on Kijiji to a local fellow gamer that had his video card blow up, and didn't have enough $ to buy a new one. Gave him a deal. The guy was so happy, it was like Xmas for him. I knew that this ASUS 7950 will have a great home. So I said Good Bye to engine #2.
When this card is retired I will box it for display. Been through so much with it, still my number 1 engine. When something is this good, you keep it in the Fam'. Still works great. Thank you ASUS & AMD for making kick ass products! Over & Out! Peace! ;]

Provide any additional details you wish below.  
 
Re-using the mATX case, psu and my hdd.  
 
Things I like in a computer - Quiet, cool, powerful.  
 
I understand my current case is complete trash, so if someone who knows more could recommend a case (within the budget) a case that could contribute to keeping my pc cool, and quiet. I've noticed during the summer my pc will act as a radiator and my room temperature peaked at an astonishing (for me, here in the UK) 39 Degrees. My student room isn't well ventilated, and while it may be great this winter coming, I don't want to experience the sweat fest that the last few summers have been with this pc.  
 
Also, a replacement GPU isn't an immediate grab, but I think i'll be in the market for something soon, as my 7970 was purchased 2nd hand from a bitcoin miner, and now after a few years of use, is slowly starting to die, as random screen tearing, sudden display crashes, crazy flashing during running fullscreen programs, even such as youtube, which never happened when i first got the card.  
 
If someone could squeeze something more powerful and modern into the budget along with the new cpu/mobo/ram combo. I mentioned the 970 my friend is offering, but I don't know if its worth it, or what I need. If it helps, if i could've found a New RX 570 at RRP (UK around £180) I would've gotten that, and gone over budget.  
 
Don't know if I left anything out, but it might be worth mentioning I have no brand loyalty, or favourites on Intel vs AMD, or nVidia vs radeon (I can't afford to). Just the best value for money, and I'm not afraid of second hand purchases, which is why you will see so much come up through what i've listed.  
 
If anyone needs more information, just ask and i'll try to respond within 24hrs.
Thanks in advance to all the help;

I took the plunge - 2x 7970's on their way for potential rig - I have no idea what I'm doing - Help appreciated!

So since this past Spring break, my brother in his all powerful insider knowledge on this strange thing named BitCoins introduced me to this bandwagon. I've since joined in and bought all I could muster with the funds in my bank without ruining myself and have thus far reaped a beautiful profit that my wife deems pleasant. This is, of course, something EXTRAORDINARY. Ahem. So I decided to wager my trust I've earned with her with said investment, and have decided to use a few more funds to build a mini miner. Obviously this won't be the mega tank that you see all over Youtube, Just a simple machine that may have the potential of 1.6GH/s is my hope.
So this is what I've bought so far:
Total thus far after Rebates & Selling Games: ~$1300 USD
Estimated 1.6GH/s with profits beginning in ~85 days (Before crash, of course XD - Now who knows!)
Great thing is if all this goes kaput, I'll at least be able to resell it all! :D
I have a monitor around for initial setup, and all the other obvious peripherals. What I am in need of are some tips or links in setting these 2 guys up. I'm somewhat new to Building a PCI-E Rig, but I'm sure its just as simple as plugging it all in, which I've done countless times before. I know that if I'm on Linux I won't need any dummy plugs for the DVI outputs on the other cards for it to be recognized by the OS. Can it be run purely all on a USB drive? That's one thing I'm a little unsure of.
Mostly my questions consist of:
I don't care much for people bantering about how difficult it is now to mine, or how ineffective this might be, I've read my share about that. I plan on just having this run in the corner of my little apartment for a few months while I go to school/work/walk the dog/etc... I would like tips or any insider info on other fellow 7970'ers on how to maximize my performance with these two cards at my disposal. And of course those who do help me in my time of need and once it's all beautiful and vampiric-sparkly like will get Brownie Points in the afterlife.
Last computer I built was back in 2004 so that I could play Half Life 2. And I was on a budget back then too. So I'm not too savvy with all this new cooling hardware and techniques as I've never had to deal with things that exceeded 4x AGP.
I'll post pictures and videos of all the fun I have with this adventure :D
Update
Thus far I have only received my two 7970's and boy do they look beastly. I've never held a card that manly before.
2nd Update
Everything came in! Goodness it's difficult to do a headless Linux Box! for sake of time, I think I'm just going to buy a cheap sata harddrive.
3rd Update
So here's the final photo of it running with 2xx7970's
I'm still waiting for the riser cables to come in to mount the other 3 cards.
I haven't uploaded the videos of me building it all just yet (btw I sucked at putting it all together XD)

Is a 7970 still decent?

Hey all recent PC builder here. A couple of weeks ago i built my first pc. A couple of years ago my buddies and I decided to try bitcoin mining and we bought 2 7970's. Needless to say the venture was a total flop and after years of gaming on console I decided to bit the bullet and jump on board. Since I already owned one of the cards I used it in my build: RAM: Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3 1600 CPU: AMD FX-8320 HDD: Hitachi Ultrastar 1TB GPU: Radeon HD 7970 (Sapphire) MOBO: MSI Socket AM3+/AMD 760G/DDR3/CrossFireX/SATA3 and USB 3.0/A&GbE/MicroATX Motherboard 760GMA-P34 (FX) Monitor: Acer G226HQL Bbd 21.5-inch.

Don't build a cheap PC, buy a badass one from 2 years ago.

Seriously I see all these builds show up on this subreddit, and they are always some AMD 6 core mediocre system. That's great and all, and everything probably has some kind of manufacturer warranty, but here's another option, buy a badass PC from 3 years ago.
So most people's "cheap builds" are $600 that I see on here. You can get a Quad-Core PC for $200-$400, that may even have a decent video card. If it doesn't, try to get it closer to the 200$ range, and just buy a good card with all the money you saved.
For $600 I've gotten older gaming PC's with SLI systems on craigslist, that some dude probably spent $2000 on in 2010 for World of Warcraft.
For $1000-2000 I was able to get a computer built to be a bitcoin miner from someone that built last year that had a gulftown i7, 4 Radeon 7970's, 16gb RAM

[Build Complete] BitFenix Prodigy APU/HD7970 based Litecoin miner/HTPC/Home file server built from (mostly) spare parts

Please note that the only parts I had to buy were the Prodigy case, ITX motherboard, Seagate HDD, the 230mm Fan and the optical drive. Also the prices don't reflect what I/others paid. Also I live in Australia; however the AU partpicker was missing some items.

Other notes are that I would strongly advise AGAINST using this motherboard, I had to RMA my first one. The replacement was supposed to be revision 2.0 however is 1.0. This is why I purchased the 230mm fan (in hopes of avoiding another fire!)
I didn't end up using the SSD as its just an HTPC/miner. It mines roughly 690Khash/s on the 7970; and around 110Khash/s on the APU (mining with Scrypt for Litecoin, not SHA-256 for bitcoin) 7970 hovers around 68-74 Celsius with room temps between 23-28C. No thermostat on VRM's unfortunately.
I feel confident this build is complete, no parts to add. I use Filezilla server as a file server as I can access this from anywhere in the world The A10 is at stock speeds as I don't want to push the VRMs on the motherboard and risk another fire. This gives more than enough power for blu-ray decoding, and other HTPC duties.
Very happy with this build. If anyone has any questions or comments I'd be glad to hear the feedback. Thanks

[Build Help] Not sure about 3-way CrossFireX

So let me preface this part list with a little background to explain the weird part selection. My friend and I are looking to get into Bitcoin mining, and it was recommended that we go with a 3x7970 GPU configuration. Will this motherboard/case/GPU combination work in CrossFire configuration? And will the power supply be enough? PCPartPicker has never steered me wrong before, but I've never tried to use CrossFireX, so I don't want to buy something I'll without getting a second opinion...

[Build Help] my first built PC: bitcoin rig two 7970s with occasional gaming

I'm building mainly a bitcoin mining rig with occasional gaming, and would love your help. I've never built a PC before but look forward to it!
Two 7970s have been purchased for a total of $900 including tax because it was good sale. Now the rest I'd like lots of input to decide upon. I want it to last as long as possible. Am Canadian (in Toronto) and a student. Willing to put additional $600-$1100 max into rest, nothing else bought. The main thing is it will be running 24/7 at max settings, and would shut down mining for occasional gaming.
A very knowledgable technician at TigerDirect gave me a great start but now I need to get more feedback. Looking for advice what to get, from where, and why.

Run down:
• COOLING? - air or liquid? - liquid is ruled out due to expense, since it's been explained to me it costs ~$600 for the assembly to liquid cool the cards directly. Seems pointless to get CPU cooling for the 1-10% time I'd use it for gaming.
• MOBO? - this is the biggest part want help with. I have no concept how to select between the suggestions Sabertooth Z77 (Intel) or Gigabyte 990FXA-UD3 (AMD). My understanding is the bus capacity is 16X for two cards is good just for gaming I'd do, otherwise wouldn't matter for bitcoin. I'm willing to invest an additional $100 above these if the quality of the parts will really last longer, but I don't want needless expense.
• CPU? - i7 ruled out as unnecessary expense, I'd get i5 if Intel. AMD is more power-efficient, but for at least the next 6-12 months I won't care, my rent includes electricity. My understanding is any performance difference of i5 vs. i7 would be A) neglible at 15% improvement, and B) only for video editing which I'd only do a few hours per year max, or never. If I were to get an AMD, an AMD FX 8320 was suggested. It's 3.5 Ghz for $160. Need help choosing between AMD or Intel. OVERCLOCKING - Also note my friend is considering overclocking speed of cards, underclock memory, and overclock the core for me.
• CROSSFIRE - desired. don't know much about.
• POWER SUPPLY? - my understanding is Corsair is a good reliable brand, for a few bucks can get 3 years warrenty for over-the-counter. know there's 4-6 tiers like AX HX TX CX, was planning on getting cheapest CX unless I understand the expense is really justified. i'll stay away from no-name brands, but don't know others. Also dunno exactly about power consumption or margin of error.
• CASE? - a case that fits, so please note the massive size of these cards, consumes 2 slots. Want lots of air cooling to mitigate costs. Aesthically also highly considering a plain white exterior to be painted... but the whole case is lowest priority for now, I want it mining bitcoin soon exposed directly to air for a short while, then can leisurely acquire case.
• MEMORY? - 8 GB was suggested, Kingston, Hyperx 1600Ghz. no clue what matters here.
• HARD DRIVE? - I want SSD, Samsung's 250 GB for $230 was suggested. I can use a spare regular harddrive to begin with to get started, add after.
Have looked at TigerDirect and NewEgg, can also look at NCIX.

[Build Help] Computer upgrade soon, need help picking out a case and water cooling.

In a month or two I am going to upgrade my PC's case and motherboard to new ones (i7 920, I will miss you) mostly because my case is falling apart and bloomfield CPUs are a bit hard to get by nowadays.
I have been thinking about water cooling for a while because I mine bitcoin with my 7970 and it's generating quite the heat (not to mention the sound).
So, to the parts I will be running in the end:
Cooling should be applied to GPU and CPU.
Now, I would prefer non-full tower but if it's required by the water cooling, that is okay. I want a window on it.
Budget: max 400€ for the cooling system. 200€ for the case. I don't care if you hit or miss the budget, it is what I think is a reasonable cost, I can pay more.
TL;DR; Need help with a water cooling setup and a case for the parts listed above.

I based the GPU/CPU on benchmarks but 2000€ is way too much for me, I can spend 1500 - 1600€ max also i'm planning on using it for gaming obviously but also for bitcoins this is why i'm doing a intel/amd combo ( I do plan on overclocking it )
So yeah I want to have the best computer without spending too much on it.
Best regards. (sorry for my poor english i'm french)

[Build Help] A friend has come to me for advice on his £600 budget gaming build.

So I've given some critique to this build, but I figured I'd come to the experts first and see what you guys can cook up.
Firstly, his suggested build to me is:
Mobo: Asus M5A78L-M/USB3
CPU: AMD FX-8320
GPU: AMD Radeon HD 7970
Generic disk drive
8GB ram
SSD: 500GB Seagate SATA 2.5-inch Solid State Hybrid Drive (SSHD) 6Gbps 5400rpm
Case: BitFenix ​​Prodigy Mini-ITX case
PSU: Solid Gear ATX12V/EPS12V 650-Watts Power Supply, Black SDGR-650E
Assume all parts to be purchased on Amazon.co.uk
So, my immediate impressions are that the motherboard is a bit on the cheapo side. I personally don't know much about AMD CPUs or their associated motherboards, but that's how I felt.
The GPU seemed ok, but I'm not sure if prices are still inflated by the whole bitcoin bonanza. Maybe I should recommend a gtx 770 instead?
I'll advise him better about the brand for ram and disk drive, that I can do myself.
He's chosen a big expensive SSD and no HDD, I'm debating whether to advise him to skip the SSD and get a 2TB HDD instead since 500GB seems small to me, for the price.
No idea about the case, no experience with mini ITX.
PSU seems shady as all fuck but again I'm not an expert.
Build seems a bit of a mess to me, so any advice rendered would be extremely useful.
Thanks in advance for any help.

Me and 2 friends are going in to bitcoin mining!:O Advice/tips welcome :)

So me and 2 friends have been looking at bitcoins for a while now and we were going to preorder BFL ASICs but having not seen them ship anything and the earliest shipping date as predictable as the rapture, we have decided to GPU mine until it's not worth it by which time we should have a sweet gaming rig :P
I used the mining GPU comparision to find out what was the best card, after much calculating and hunting I gave up on the idea of trying to find 4 5870's cheap and decided that the top end was probably the best bet, especially looking at some of the MH/s out the HD 7970 when overclocked.
I did a lot of shopping around and I think I found some good parts at a good price too.
1 x GIGABYTE GA-970A-DS3 AMD 970A (Socket AM3+) ATX Motherboard 1 x GIGABYTE WindForce Radeon HD 7970 OC 3GB(I want to overclock this to 1100MHz) 1 x 750W Corsair Builder Series Modular Power Supply 1 x ARIAnet Titan Black Midi Tower Window Gaming Case 2 x Arctic Cooling F12 Quiet Case Fan 120mm (lots of fans:D) 1 x AMD (Piledriver) FX-8320 3.50GHz (4.00GHz Turbo) Socket AM3+ 8-Core Processor 1 x Arctic Cooling Freezer 13 Quiet CPU Cooler 1 x 4GB (2x2GB) Corsair Value Select 1333MHz CL9 DDR3 Dual/Quad Channel Kit
The only things I don't need is a HDD and Optical drive as I already have spares.
The total cost of the PC is £680, bearing in mind the GPU is £330.
The motherboard supports Xfire so I could have 2 7970's.
One of my main questions is should we get a 2nd 7970 NOW or LATER?!
I've used the calculator to find out what the approximate hash rates are and this rig could pay for it's self in 3 months, sooner if the BTc value rises. We have also taken in to account the weekly power cost and worked it in to the return rate.
Advice or suggestions would be great:) Thanks
