Ok, with Halo, Half Life 2 and Doom 3 coming out at some point soon (hopefully) I think I'm going to need a new video card. Any one have any ideas what I should get? I've always went with Nvidia but with those benchmarks that Valve released I'm not so sure. And am I going to break the bank with this. It's a shame having to get a video card to play video games that cost more then a game console does.
