First post on here guys...ran into something that I can't figure out by myself. I own a Power Mac G4 450 DP and want to upgrade the cr@p Rage 128 16meg card that came with it 4 years ago. I know I have an AGP 2x slot but I have no idea what video card to get for the $$$. I just need something for games/simulators like Warcraft III and x-plane...nothing crazy...just don't want the horrible quality and frame rates anymore. Any ideas??? ATI, Nividia?? oh..and can I use a AGP 4x card in my 2x slot??? I don't really know how that compatibility works.
