Hey guys since the 300 series drivers and my 680gtx my windows is very laggy , i mean when everytime i drag or re-size or just lower a window to the taskbar its very slow and then it can speed up back to normal smoothness . I'm running 3 LCDs but not in surround so i have no idea what could cause this problem. also my brother has a first gen i7 with 2 560Ti , 4 screens and he has that problem too since updating. In window 8 it doesn't happen but 7 it does. Any idea and does anybody else have this problem?
