Reet, old nvidia 8600 gt broke, so I got an xfx 8600 gt xxx because it was nice and cheap, anyways, got the ddrivers for it, but when I load up fallout it detects a 7900 gs. I don't know if this would do anything or not but either way I would like to know why, even when everything else detects an 8600gt. Nothing wrong I can still play the game I was just wondering why and all, anyone got a similar thing? Or know why its happening?
