I would, but I like to play games and when I do I usually stop the cpu and video card. I'm not too familiar with the bigadv. I know how to turn it on but I am under the impression that you have to leave it running 24-7 to benefit.
I will check my qx6850 on this wu, i dont recall any wu's being slow even the 6701 will gimme 7k ppd.
My guess is your'e using more cpu than you think, folding by definition will use idle clocks, so if your'e browsing web, listening to music etc etc etc etc you will slow down folding.. when TPF is normally 4-7 on my qx6850, it will go up as high as 30min when gaming..
