I'm in the early stages of planning to buy a new Mac Pro. Just waiting for Snow Leopard before I pull the trigger. I've read over the Apple site a few times, but don't really understand what the practical differences are between the Nvidia card and the ATI. I'm primarily using After Effects & Photoshop, driving 1 (may go to 2) 23" DVI display, and may occasionally play some Windows games (BF2, et al) under Bootcamp. Given that kind of a workload, will I see any benefit to ordering the ATI card, or should I spend the money on more RAM instead?
