My dad just bought a Radeon 9200/128 video card for his PowerMac G4/350Mhz. "yikes". I keep on telling him that he didn't gain much speed because that computer has a 350mhz cpu and a 100mhz bus, but he won't believe me. Am I wrong, or is he wrong? How much speed gain do you think the computer profited by, with that video card in it?
