Allan, Here is a link to Adobe's knowledge base article on GPU acceleration support for Photoshop CS4/5: http://kb2.adobe.com/cps/404/kb404898.html Contained therein are links to testing done on a variety of video cards. It should help figure out if ATI is worth $200 vs. Nvidia for your needs. Hope this helps, --Perren On Aug 13, 2010, at 11:30 AM, Allan Rube <arube570 at gmail.com> wrote: I am going to buy a new Mac Pro with the 3.3 processor (6 core). I am a photographer and use Photoshop and Nik’s Nikon NX more than any other applications. Would the stock video card be the one to et or should I spend the extra $200 to get the higher end card? Opinions please.
