Serveral people in this thread have claimed that ATi still has better image quality than nVidia, especially in regards to antialiasing.
The GeForce6 series has many antialiasing modes at its disposal. One of them is 16xS, and it can be activated through the nHancer profile editor.

You can also use rivatuner, but, enhancer is more elegant since you can set your AA options on a game by gaem basis, something you can't acheive with RivaRtuner.
16xS comprises 4x RGMS MSAA and 2x2 SSAA combined, and I would contend it is easily the equal or better of anything ATi can offer AA wise. It also has the advantage of increasing texture quality do to the Super Sampling component.
I used this mode to generate the screenshots below. Unfortunately, due to hosting limitations I can't show 1600x1200 sized images so 1024x768 will have to suffice. (The screens haven't been scaled down, the game was actually set to 1024x768). If someone can host a couple of images at 1.9mb (approx) each, I can provide examples @ 1600x1200.
The display driver used was 76.41, High Quality settings, all optimizations off, 16xS AA, 16x AF.
I encourage those who claim better ATi IQ to provide evidence of their claims. The game I used for the pics is Mafia, because it is very demanding on both AA & AF to look its best.
Screen captures were performed using fraps 2.5.4
The resulting .bmp captures were then converted to jpegs using irfanview V3.95 You can see the conversion settings in the link below. I'm confident these images are as close to the .bmp originals as .jpg will allow.

(Yes, I now have a GeForce6 6800GT - the Leadtek model. Yes, I still have my 5900XT, it now resides in my spare machine).
Oh yes, a comment on the actual subject of the thread - pricing. I remember back before the release of R300/nV3x that a certain ATi troll with the handle JDPC (on a different forum) loved to endlessly comment about nVidia's high prices and how such a situation would never occur if ATi were market leader... I wonder what he has to say nowadays...
