I'm a AMD CPU user, and now I only have ATI graphics. If a few years
ago the nVidia support for linux was much better, now both the kernel
driver and ATI catalyst driver work for me very well.

As a note, I usually use the proprietary ATI driver on my personal
computers to use openGL (like with stellarium).

All the above, AFAIK, I must say.

I also read about nVidia ahead on using the GPU to do some of the CPU
work, that seems interesting. Again, if it is, I am confident ATI will
get there too.

So, just to say that, in my opinion, there's no reason to trash ATI
nowadays regarding linux, even if you think (and you may be right)
nVidia is better. Not that you did it say it, but it may seems
As on Intel/AMD cpu, price as a word there too.
