I just posted to the Video section of the forums with a request for input on the best graphics card to upgrade my G5. Thought I'd put a link from the PowerMac category as some of you might see it here and not there. Thanks for your input!

ATI Radeon X800 XT.
But good luck trying to find one especially at a reasonable price.
ATI has discontinued production of all Mac AGP cards.
