I'm doing more gaming on my PC, but I seem to be able to run the games I'm playing at this monitor's full resolution (1920x1200) with full detail at acceptable frame rates on my current computer. It's got a Radeon HD 4850, which certainly isn't top-of-the-line. I figure I'll stay in the middle of the road as far as video card. I'm thinking I'll go with a 5770 for my new build, for the DirectX 11 support as well as HD audio over HDMI. If physics processing starts meaning more, maybe I'll go back to Nvidia at some point.
