To the Folding Team
From my experience on folding with single socket CPU's, you are better off saving the i7 to feed your GPU's. AFAIK the rule is still 2 cores per GPU, which causes you to gimp the i7's folding power to make sure the GPU's are properly feed
The GPU's don't have to be water cooled, unless you want to. Many of us run them on their stock cooling.
I will give you a BIG tip that I have learned over the years of folding. Set up a separate rig that is dedicated to just folding, instead of using your main computer. I found out ( using my main gaming computer for folding ) that I would shut down my folding to watch a movie, encode a movie or MP3 CD, Ect, Ect. This takes away from your GPU's or CPU's folding power and majority of the time, will cause F@H to crash or have a serious impact on your PPD.
Hopefully some others will also chime in with their knowledge of folding
