What does REDHAT recomend for 3D video card?

[Stephan Schutter]

I have got the impression that RH does not respect NVidia much because
they will not give their code away... and well... sometimes there are
issues with the RedHat kernels and nvidia (sometimes they are compiled
with a different compiler than the one that is distributed with the
system?). Soooooo.... The big question: What video card am I supposed to
use?  What DOES RedHat recommend?
