I have a Mac G4 533MHz PowerPC 768 MB SDRAM
ATY, Rage 128Pro card...what card can I upgrade with??
Again, be aware that flashing third-party PC cards for use on a Mac is hit-and-miss. This used to be possible back in the days of 3dfx Voodoo cards because the PC and Mac versions sold were actually the same exact card with different firmware (meaning it had the memory space for each firmware). However, don't expect this to be the case nowadays.
If you take this offer, you're doing so at your own risk.
