I'd been thinking of upgrading to a new video card from my ATI 9600XT. Call of Duty and Doom III is kind of tough on it. So, I get on Tom's Hardware Guide and decide for the money the ATI X700 Pro or GeForce 6600 GT look pretty good. Then I realize these cards are only available in something called PCI express, not AGP. WTH is that?? Guess I've been sleeping. When did PCI express come along? These new cards are not even available in AGP (yet). Am I missing something? Seems dumb for card manufacturers to introduce cards with an interface most of us can't use. I really don't want to build a new system just to use update my graphics card. Guess I'll wait until they come out in AGP.
