Im running a G4 350 model w/ 384 Ram, and i think a 128 rage graphics card. I use my comp mostly for Word, video, and gaming. My friend said that game speed is dependent on the graphics card, not the prosessor speed. Is this true? I would think that a complex game like Red Faction, Quake, UT ect. Would use about 100%. Well is it worth upgrading my PCI 128 Rage (would I notice a speed improvement and be able to run games with a better graphics setting)? What model would you suggest? Thanks alot.
