Hola,
Few months back I bought an evga 8800GTX AC3 KO. Plugged it into my evga 680i SLI motherboard (122-CK-NF68-A1) and everything seemed to be fine at first. However, occasionally I would experience crashes, mostly when I would play something that would stress the card a lot. Such as HL2...
I looked around on a couple of forums and nobody mentioned anything similar, so maybe it's my system. But since I switched to 71.xx and then some leaked 76 and 77 drivers from my 66.xx on a 6800GT I experience weird stops during games. Tested OpenGL and DirectX and it happens in both, most often...
