Also having weird crashes while playing the BC2 beta, about 10 minutes in the graphics tear and the game does a CTD. Then if I go on the net some graphics will look majorly distorted, and if I play any movie file it just looks distorted to the point of no visual and I have to exit it. When I restart, everything is back to normal. I'm starting to think it's either the new drivers or my new OC but it's only from stock to 3.7Ghz and temps at over an hour with prime never go above 42c, video card stays cool at also at full load. A 550vx should power this system no problem...right?
