Seems to offer no change in performance along the highend card line, friends with Ti4600 and lower said Anti Aliasing ran a little smoother, however the shadows appeared to flicker.
I built my current computer from an excellent set of parts and am currently running on a respectable but not ridiculous ATI card. For those of you in the know, what would be the best card be for me to upgrade to in the $300-400 price range?
