Yeah, the GT should be $400 at most. If you are actually looking at an Ultra, then it is a toss-up between the the XT and the Ultra - Ultra has better features, the XT is maybe ~.5%-1% faster on average. It's up to you which is more important. Also, I personally feel that the 6800 architecture shows more potential on the newest engines, i.e. Doom3 and Farcry, and I don't expect it to be too bad in HL2, either, although the X800 will probably win in that category. Anyways, I suggest you look around for a sub-$400 6800GT, it's a far better value than the XT or Ultra. Around 95% of the performance for around 75% of the cost seems like a good deal. In fact, bestbuy has the BFG 6800GT OC for $400, and it's overclocked to 375MHz, just 25MHz shy of the Ultra! It also has a lifetime warranty. In fact, bestbuy usually has that 10% off sale during thanksgiving, so I imagine you'll be able to get it for $360 in a few weeks. That's just my recommendation, though, if there is no problem spending $500 on a video card, then either the XT or Ultra will serve you well. Oh, BTW, don't get the X800 Pro. It's just not a good value for the money compared to the GT.
