I'm playing at 1600x1200 on my GeForce 3 right now because I can't use FSAA without that FSAA glitch. I prefer to play at 1024x768 with FSAA. Anyways I disagree that you can't tell the difference at anything above 800x600. It all depends on the size of your monitor. On my 21'' monitor, 800x600 looks blocky. And on a large screen TV with S-Video 800x600 looks even blockier, without FSAA of course.
