I'm not really too interested in raw gpu power myself (it's all good as long as you got something non-super slow) as the rendering features that make games look really good. Can someone in the know summarize these features and which ones are most important? I know it depends on the software too. But is anisotropic filtering any good? I think environmental bump mapping might be pretty sweet, right?
I turned on AA when running a 3dmark, and aside from lowering the score by 1000, it actually made the images seem moreblurry! So I guess not all of the extras are necessarily good in every case either.
I'm curious what are the really good features essential in a card?
