As for the quality and options of the AA between the brands, I am not knowledgeable enough to say, but I will say that I can't tell a bit of difference between the two brands myself.(I own several of each brand) I suppose this is a pointless discussion though, he is looking at a lower price point and I missed it while reading the OP, so we should drop it.
Between the two he listed, I'd go with the 470. I'd recommend the 570 over the 470 though, if you can afford it.
I'm not so sure about the emboldened. Performance decreases before you exceed the VRAM limit. The extra textures that come with the higher resolution have to be placed on the wireframe. This is what the ROPs do (calculating the coÃ¶rdinates). Though it's no use discussing this further like you said. Let's not stray too far from the subject.

The 69xx cards seem to have the same thing called EQAA and is MLAA available on nvidia currently?
Allowed to do what? It's just a different algorithm nVidia uses through the drivers. You can enable SSAA through the nVidia CP comparable with CCC.
You're right about EQAA being more or less a copy of CSAA though it doesn't have alpha-to-coverage. Edge-detect and how it samples is more or less the same, though 8xEQ is the max for Cayman while GF100/110 can sample till 32xCSAA with alpha. About MLAA however, technically nVidia can. The 7800GTX equivalent in the PS3 uses it
No seriously MLAA is far from perfect it even blurrs detail, I've tested this on my HD 5770. EQAA is far better and SSAA is still the beast (or a monster from a geometry computational perspective
You could test this out. Try SSAA in Mafia II or Fallout NV for example (Radeon Pro). Compare it to MLAA and EQAA.
Just noticed you have an HD4k card so you can't test EQAA.Edited by TheBlademaster01 - 1/1/11 at 7:59am
