Doom III should definitely be a good step in the direction of games taking advantage of new features and speed of these newfangled cards comming out. But just in case you didn't know, check out Bethesda's new game, Morrowind. I have an athlon 1400, with a geforce2mx, and it runs pretty slow in some parts. The graphics are really reallynice. I am actually upgrading to a geforce 4 4200 just for this game. The water supposedly looks really nice (nigh photorealistic) if you have a geforce 3 or 4 because it takes advantage of the pixel shading capabilities. I don't know what other games cause I don't play too much. But you should definitely check out Morrowind.
