i c. well spec wise, it would be much easier to read a few reviews on the 8800GT, rather then listen to me blather on how perfect it is. what i do know is that it is just slightly below, and even beats at lower resolutions, the 8800GTX. it will play Crysis on High with a good system besides the card, and can play new games like farcry2, fallout 3, Brothers in arms, hells highway, World in Conflict...
and it will max out WoW with ease. i've personally ran WoW, Oblivion, and Firefox simultaneously (my brother was playing Oblivion and i didnt need to close it) and it did not lag.
