I currently bought the XFX Radeon HD 6850 with the MOH game bundle. after installing the driver and the game, started the games and once in the main menu it began to freeze and then crash on me. I then tried playing Rainbow Six 2 on it and things look sketchy. With the pixels would act up. That wouldn't happen with the HD 5770 card that i had prior. Anybody have any ideas why this would be happening.
