Hi, currently I'm playing a game running at a resolution of 1920 x 1200. It looks really beautiful with little lag. I was going to upgrade to a 30 Inch with a resolution of 2560 x 1600, but I'm worried that my Mac Pro cannot handle it. Have anyone try playing game at 2560 x 1600 on a Mac Pro? Reason I want to ask first because I do not want to put down a few thousand dollars and be disappointed. I have a Mac Pro 2.6Ghz with ATI X 1900XT.
