I have an older Dell Dimension XPS D333; P2, 333; 128 MB ram; W98 SE. It has a standard AGP card, 4mb [stb velocity]. I want to play games on this PC. Can I safely use an AGP Pro card in the PC? If yes, which 64 MB card do you suggest? If no, which 64 MB card do you suggest. Thanks for your attention to my situation.
