CPU vs GPU folding - best for budget build?

post #1 of 2
Thread Starter 
Hi all,

I am back to folding again on my current rig - specs are below and not too bad, just installed a Coolermaster Hyper 212 Evo so im a bit happier about leaving the CPU folding for a longer period of time due to the fact its running 10C cooler than when it was on the stock cooler!

I am thinking about maybe next year/ongoing project to build a small folding rig that I can setup and leave running and not worry about it lol I have a few ideas of what I might want to do, it will be a low budget, basically as cheap as possible but powerful enough to actually be worth it, here are a few options:

Barebones PC with multicore CPU but small hard drive and no graphic card
Barebones PC with very basic processor but with 2 x graphics cards
Twin CPU (or more) server motherboard (seen some dual opteron boards going for £20!)

What route do you think I should look at going down? I know that there are changes for the bigadv WUs going on, so im guessing that I would need some fairly beefy cores to be able to fold those to get the best PPD. Would be best with a lower clock speed and a few CPUs or just 1 multicore CPU at a higher clock speed?

What does everyone suggest I should do and I will start reserching!

Twin CPU might be your best bet, if you can manage to get at least 12 if not 16 cores in total. That should still be able to handle the -bigadv after the changes.

 

Failing that, Fermi folding is out-performing SMP folding for me in terms of PPD.

 

OC'd GTX 580 = 20K PPD

4.7 GHz 2500K ~ 16-18K PPD

 

(Those stats are simultaneous. I'd see a very slight bump to the SMP if I wasn't folding on the Fermi, but it's nowhere near enough to make up for the Fermi points.)
