I just got a new iMac G5 2.0GHz with the Radeon 9600 that everyone has been screaming for because it is approximately 5-10% faster than the Geforce 5200 Ultra.
I just figured out why it is faster. I was just doing some OpenGL programming and I wasn't able to draw antialiased polygons in the program, so I went through all kinds of bug hunting to find out why. Eventually I found this:
Maybe I'm silly but I do prefer a 5-10% slower card that actually does what it's told and doesn't cheat by drawing aliased graphics when the program wants to draw antialiased.

If you are using an ATI 9600, 9700, or 9800, YOU ARE SCREWED.
Polygon antialiasing is NOT AVAILABLE on these cards. Hooray for "progress".

The Radeon 9600 and later cards from ATI have no hardware support for AA
polygons, so unfortunately there is nothing that can be done to address this
missing driver feature.
As far as AA points and lines go, those features are present in the
hardware, but not yet exposed by our GL drivers. We do have plans to
implement them, but I can't comment on when drivers will be released with
those features supported.
Yes, this breaks many existing applications. No, ATI doesn't give a ****.
