So I am going to order a dual 2 G5 here in the next week, without fretting about the possibilities of the future updates, and I was wondering. The graphics card that comes with the machine, the ATI Radeon 9600 Pro with 64 mb of DDR ram. I know that card is an EXCELLENT card, but, I was wondering if anyone knows if the ATI Radeon 9800 pro is worth the extra 270?? (edcuational discounts) Also, do they make the 9800XT pro for the mac yet, with 256 mb of DDR ram?? Thanks, and any other recomendations or advice would be helpful. Thanks!
