Well, I'm happy with my 9200 but I can't say if it's better or worse than any other card. The video quality equals the GeForce 2 I had in my previous computer.
Since I replaced the fan (ati's fans are crap anyway) with a heatpipe it makes no noise. And since DRI is supposedly working with the Discovery II I will get accelerated 3D in Linux as soon as Sven releases the kernel.
So I am happy
