I currently use a dual G4 867mhz system (I believe it was the last revision
of the G4 line before the G5) which still has the factory installed Geforce
4MX video card.

I am in the market for an upgrade and was told that the ATI Radeon 9000
would be a wise choice as my PowerMac would be unable to take advantage of
anything beyond that. I am primarily looking forward to newer games due to
be released such as Doom III and World of Warcraft and would prefer to play
these newer titles at a 1024 x 768 resolution with performance settings
slightly above the default (especially textures). Would the Radeon 9000 be
able to accommodate my needs?

Thanks in advance.
