Sup guys, I have an NX7900 GT (Nvidia 7900 GT), 2 of them actualy and I've been facing a problem with a couple of programs like World of Warcraft, Playing Vedio on any program...the problem is that whenever I move in World of Warcraft the screen around me shows like it is rendering frame by frame but not slowly...this is gonna be tough to explain... ok imagain youre in a first person shooter or a 3rd view game and you look around you, what happends is for example if Im looking at a tree, and I go from right to left or the opposite, I see that tree rendering frame by frame but very fast it looks like its breaking...anyone got what I mean or knows how to fix that? and oh 1 more thing I installed the driver that came in the CD itself and I have a purple line on the left side of the screen...HELP!!!
