so you are the one lead me by 1100 points, do not worry about me, I only use my pc when I get home, 5 hours per week day, 10 hours on the weekend, my ppd about 3000, so (6*5+10*2)/24*3000=6000 per week, I will never catch you.
the 8800 gts 640 MB is a decent video card to run folding, I found out oc the shade frequency will incrase PPD almost on 1:1 ratio. and VGA ppd is not heavily depend on cpu, I try my x3210 stock frequency and oc to 3.4 GHZ. the PPD remain about same. i will list my detail set up tonight.
