I have an EVGA 7600gt KO, and I have an interesting problem. It seems that when I OC the videocard it causes MAJOR stuttering. I'm talking about everything just freezes for up to 15 seconds(estimate) and then it resumes. I know the card is already oced from factory, but it seems odd that it would cause this issue, instead of artifacting or high temps. I managed to score 5600 in 3dmark01 lol. But when I clocked back down to stock, I got 17k.
