Advice on my beginners BTC GPU mining machine

So I'm looking to build a BTC mining machine.. I know mining has taken a hit and is getting less and less viable for a single machine to pull off, but I'm still interested.. I know I probably will never recover the cost of building my mining machine, but as a enthusiast to the whole thing I'd just like to give mining a shot..

I also have some questions.. How important is RAM for a mining rig? I know you want AMD GPU's for GPU mining, but what about a CPU for GPU mining? Do I need that big beefy CPU? Should I get a AMD CPU? Also, I know the 295X2's are relatively new, but does anyone know if the cooling system that comes with them will be adequate enough for a build like this?

Any help/advice is appreciated!

  1. If for some reason you get free electricity, you would need years to mine enough to pay for half of this system.
    Also, using gear this high end for mining seems like a sin.
    Good luck though.

    I would be joining a mining pool more then likely.. And price is not a issue, I've got extra money and I know I'll more then likely never recover my costs.. I'm just interested in the whole concept of cryptocurrency and would like to be a part of it.. Plus, I'm not opposed to mining things like litecoins either..

    Does anyone got any advice on the build? Or any way to cut costs outside of the GPUs?? I'd really appreciate any help to the questions I asked in the first post? :)
  3. You'd want to mine LTC, not BTC. The network hashing rate for BTC is now so high that only really expensive ASICs (requiring business-level investment) are even work considering (if you like high risk).
  4. But I don't think you need a cpu that is 1k...
  5. Why not just choose a cheap cpu. And 4 way crossfire 280x

    Yeah I've consider mining LTCs in the hope that they later increase in value like BTCs have.. Plus I heard ASIC mining wont work for them which is always a plus.. I actually did a school project on cryptocurrency and now I'm very intrigued.. I currently stay somewhere were utilities are included so all I'd really have to worry about is covering the cost of the rig, although I don't plan to ever be able to achieve that heh
  8. Graphics cards use a lot of power. For instance, the r9 295x2 has a tdp of like 500w and costs as much as some cars, i've owned heaters that had less, and a car that cost less.

    Are 4x 280's more effecient then 2x 295's?

    Let's say I stuck with the 2x 295's, could I get away with pairing them with a cheap CPU? Would a cheaper CPU have any effect on my GPU mining?
  10. Not really, as far as I know, the GPU is pretty much all that matters.
    So if you want to be super cost effective, get the cheapest cpu and a mobo that can take as many gpu's as it can.
    Also 295's are much better than 280's, but they are prohibitively expensive.
    As far as I know the 280 is the best card for price/performance, miningwise.
    -don't take my word for it, i've just randomly read a few articles about the thing, sharing what little i know.
  11. I believe that LTC can still be mined with a CPU too, as the scrypt algorithm is apparently somewhat GPU-resistant as well as being ASIC-resistant.
    If you are doing this as an intellectual exercise, there are many different cryptocurrencies from which to choose, many of which are of little if any value and may well die, but would serve your purposes.
