We sure do. Depending on the game you play the 5850 and GTX 470 and above can run just about anything at that res. You can run no AA on that res and get away with it too seeing as how the jaggies are much smaller natively.2560x1600 would probably be the best you could get around that size. The market for extremely high res screens is low right now because we don't have the GPU power openly available to drive that many pixels... yet.
