ATI's X1000 series has the advantage of using both types of AF, and at HQ mode there is no texture aliasing to be had.
the last radeon i saw in action was a 9700pro so i have no clue whether the image quality of the radeons is good or not. i just know what i see with my 7800gt :P
and i know that this little "shimmering" doesn't appear on my old gf3ti500 and gffx5900xt.
