I am buying MacPro for Photoshop, Illustrator, photo editing, print ads, etc... no games. I narrowed my choice to 30" NEC 3090 monitor and since I already have the 244T I would also like to use it. So from Apple online store I can get either 2 x ATI Radeon HD 2600 XT 256MB or 1 x NVIDIA GeForce 8800 GT 512MB. Should I go with 2 2600's or will this not be enough? Or get 8800 to run that 30" beast and buy some other card for the Sammy like the X1900? I've heard that ATIs are better than Nvidea for Macs... I need advice please.
