These static screenshots are pretty much the same. It's not until we see the game in motion do we see the limitations of NVIDIA's anti aliasing compared to ATI's. Even 8xS AA still exhibits aliasing despite the number of samples. ATI is maintaining the tradition of more effective anti aliasing with the X1800 and X1900.

The differences are subtle but they can be seen if you look close enough in the screenshots. They become more apparent when viewed in motion. ATI's 4x and 6x is still more effective than NVIDIA's 8xS in removing aliasing. However, we can see that 4x and 6x antialiasing is not that much different if we were to look only at static screenshots. ATI's 4x mode is that good.
Except for Call of Duty which feature transparent textures, anti aliasing is still better on the Radeon X1900 than on NVIDIA's GeForce 7 series, be it 4x and 8xS. On faraway objects, ATI's 6x and NVIDIA's 8xS does a better job than both's 4x mode, but not that much. So, even if the X1900 6x is still slower than 4x on the Radeon X1900, we actually don't lose that much in image quality. Or put in another way, we really don't gain that much with 6x. The most notable gain is actually the use of HQ AF, though it may not be noticeable in all games.Let's see if those performance claims are true.
