16xAF combined with SSAA 2x = 64xAF -> Bye to all the texture shimmering problems or artifacts. And it's compatible with ALL the rendering techniques like deferred shading.
The performance is ok with old games, and some well coded games like DMC4 run at 60fps on the 8800GTX with SSAA 2x enabled @ 1280x1024. You need a monster bandwidth, but, someday it will arrive. GDDR5 on a 512bit bus could be a good beginning
