I started folding in March with an i7-3930k and a single 7970 GHz Edition. I was getting ~95k PPD after setting up the new beta core 0x17. I decided to add another 7970 assuming I would get another 45k PPD out of it, but I have gotten anywhere from 66k-127k http://folding.extremeoverclocking.com/user_summary.php?s=&u=633356. I overclocked my CPU using standard mobo profiles (Asus Rampage IV Extreme) to get 4.4GHz. I overclocked my video cards using AMD Catalyst/Overdrive to get them to 1200MHz. I haven't done anything with voltages just used pre-made profiles or increased clock speed using manufacturer provided software. My video cards are Sapphire Vapor-X 6GB 7970 GHz Edition http://www.newegg.com/Product/Product.aspx?Item=N82E16814202005. The video cards require 2x8-pin power connectors each and the mobo has a separate 6-pin power connector for 3-way crossfire/SLI. I wound up using the 6-pin connector in addition to the 2x8-pin connectors which seemed to make things more stable.
I am currently folding for Reddit, but I have signed up to help Overclockers for the Chimp Challenge.
