Yea everything looks good, definitely don't get XFX for video cards though, they're horrible. Go with eVGA and downgrade to a 7800GT because in benchmarks, the GTX only gets about 5-10 fps more than the GT, which IMO isn't worth the large price gap between the two cards. Might want to switch out the ram too.
