I forgot about this but here I am again. I set the default clocks 850/1200. And reinstalled Catalyst 10.11. And magically the screen tearing stopped during movies, and the games dont crash.. as much. Dead Rising 2, Bioshock, Fallout New Vegas, all dont crash at all. But Assassins Creed 2 and Need For Speed Shift still seem to lock up randomly, crash, or go to that weird grey patterned screen. Which is most likely the games problem not the GPU.
