i have a 7600gs in one comp, and a 7900gtx in another. both run AH well. of course the 7900 does it a lot better. with the 7600 i run 512 textures, the 7900 runs 1024 with the hi-res pack. just depends on what you want to spend. i do agree with Fulmar though, if your going to get an 8xxx series card, go 8800.
