Antialiasing quality


6X antialiasing - Radeon X600 XT


6X antialiasing - Radeon 9800 XT


6X antialiasing - Radeon X700 XT


8X antialiasing - GeForce 6600 GT


8X antialiasing - GeForce FX 5900 XT

ATI's 6X AA mode continues to be a marvel. I think it does a better job of removing edge jaggies than NVIDIA's 8X mode.
