I have a Dell Dimension 8200 with a GeForce4 64MB video card in it now. I am in the process of upgrading and I just want to know if ATI cards are also compatible with my comp? And does anyone know which is better between Powercolor ATI Radeon 9600 Pro and nVidia GeForce FX 5200? I have found those to be around the same price range and thats why I am comparing the two. Thanks.
