i can understand waiting for a new video card, for dx10, but like i'v replied to others a few times before, if your not using vista, dont even consider dx10, and like may other's have said, who knows how long till game developers support dx10....dx9 is going to be it at least for a little bit longer. so why not go for the best dx9 games.....also, how much better performance will you get with that xtx compaired to your two 7800gt's. is it better or worse....i think its only marginally better. and just looking at the anandtech bench from oblivion, the x1900xtx is considerably more powerful than the two 7800gt's in sli...but thats just that one instance...i'd look up more benches.
