I'm trying to figure out what the best video card is right now. I have a friend wanting to upgrade his, and he wants to get his money's worth. He plays World of Warcraft alot and wants a sharper picture and better refresh rate. I have tried finding a good comparison site because I know I like my Raedon 9800 Pro (128 MB), though even I'm looking at upgrading to a 512MB card, but he's looking at the Raedon x1300 (256MB). Any suggestions on either a good comparison site or a personal suggestion?
