Hi all, I'm thinking of upgrading the Radeon 8500 in my Gigabit ethernet (1.5Ghz) G4 to a 9800 Pro. I've looked all over for comments on whether or not this card gives much better performance than the 8500 on an AGP 2X machine, but haven't found much. Can anyone give me an idea as to whether it's worth it? Thanx much.
