there is a REAL 6800GT for PCIe, it's just pretty hard to find right now. Soon, it'll be pretty common, after all the A64 PCIe chipsets are available. No matter how you look at it, though, you can't do better for $400 than a 6800GT. The BFG version is overclocked by default, and comes with a lifetime warranty, so go for that if you can find it. Best buy sells it for $400, and if you can get your hands on one of those 10% off coupons you find every month or 2, you can get it for $360. The X800 Pro is just too crippled to compete. On the other hand, if you can find an X800XT (non-platinum) for close to $400, then go for that - i think it's supposed to be in the $450 or below range, but I haven't seen it for that cheap as of yet.
