Well I don't know, but My system is fine with my graphics card. It may only have 320MB, but I am running all my games on 1440x900 with no slowdowns on mostly all the games I own. Video Memory does not matter much if you are playing in lower resolutions. If you are running at 1680x1050+, then you might want 512MB or more. The big chunk you have to worry about is CPU clock speed and GPU power/PCI-X bandwidth.
