I have to agree with Cartman. ATI is currently the way to go for a video card. I go into stores right now and see multitudes of nVidia cards collecting dust on the shelves and only the LOWEST end Radeons are left (at least around me, it's that way) and big empty holes where the high-end Radeons are supposed to be. Which means, guess which cards people are buying?
It's not that nVidia cards are absolutely sorry by any means (highly arguable point

), it's just that ATI is MUCH faster, has better IQ, is more in-line with the established code-path standards, and are more respected right now and Radeons are selling like hot-cakes compared to nVidia as a result.
I would chalk it up to ATI directly supporting DX9 as opposed to nVidia's deviant cg code-path (and the fact that pixel-shader performance is slow on nVidia cards) as the main deciding factor for choosing a video card among people who are 'in the know'.
What I'd really like to see is less "The Way It's Meant To Be Played" games and more "Get In The Game" games.
