I have a PowerMac G4 FW800 1.42gHz that has no video card and I have a dual 450 gigabit ethernet with an ATI Radeon 32mb AGP video card and I have some older pci Rage 128 pros, my question is would I benefit from sticking one or two of those pci cards in there? and would the radeon even be compatible with the 1.42 in the first place?
