Hi, I saw this at Best Buy. It's similiar to the ATI X1900 XT. http://www.bestbuy.com/site/olspage...idia&lp=10&type=product&cp=2&id=1149206843643 Was wondering if it gonna work on the Mac Pro? Do I need to buy any special cable or use Titan driver? I know the ATI X1900 XT is a good card, but it's too bulky and never like ATI anyway. Thanks!
