You couldn't be more wrong. This needs to stop because it's getting annoying.

Not only is that particular area noticeably better on GF100 at highest quality AF setting vs. the RV870, but the entire image. If you go to
this page, it allows you to compare the images by putting them on top of each other, and you can
clearly see the image is better on GF100. So please, stop saying it isn't.
ATI has sacrificed filtering quality in order for their angle independent algorithm to work with a reasonable hit on performance, and this translates to lower overall AF quality than GF100 in practice.
