Depends on what you do with 3d.. (i.e.games,rendering etc... )
but from my personal experience... this is a BIG NO! NO!...
there are some other distro that does much much better than this.
bcoz redhat has (not sure really) the worse* multimedia support of all the *nix distro's out there...
unless u know how to really tweak settings... if not.. it will consume a hell alotov your time(and lots and lots of brain cells)... Suse is a good distro enough for standard linux 3d apps... or find anything else than this...
