I'd like to replace the original card with a "newer" one for the G4 Gigabit machine. I saw this one advertised and was wondering if it was compatible.

ATI Radeon 9000 Pro Mac Edition 128MB DDR SDRAM AGP 8x (2048 x 1536 Max Resolution) ADC, DVI and VGA Connectors Video Card Mfr P/N 100-433022

Thanks
