I can't afford a G5 at this point so I'm upgrading my G4. I already took it from dual 800 MHz processors to dual 1.8 GHz processors and of course it's was already maxed out on RAM. But to get back in the game with Motion I need a new video card. Ideally I'm looking for the most v-ram that I can EASILY put in my G4 without any serious modifications like replacing the power supply. It's not just Motion, I tried loading FCP Studio 2 and was warned that I had insufficient RAM (64 Megs) for that version of FCP. Any recommendations or suggestions?
