The one option I kinda wish I’d gotten with my Mac Pro is the upgrade from the Nvidia 7300GT to the ATI Radeon X1900 XT. If you take a look at Apple’s comparison, it becomes very clear why. It’s not that I feel hampered by the stock card, it’s just that the Radeon is just so much better.
At $350 for the upgrade (or $499 if you want to buy it separately), it was a bit pricey initially. Apple has dropped the price by $100 for both the BTO option and the aftermarket upgrade. $250 as an option is mighty fine. Delivery is still a few weeks out right now, but if you’re willing to wait and want to make your Mac Pro really shine, the X1900 XT is definitely an affordable option.
