I have been using Ubuntu for a few years but not extensively. With the recent Ubuntu releases, I am getting left behind because of my ATI 9600XT which I have a hard time getting the most out of it. Because of this, today I am wondering what is the best Linux distro I can use to get the most ouf of my ATI 9600XT until I can onday, get new hardware.

Besides Ubuntu and all its flavors, what is the best Linux distro out there that I can use for my ATI 9600XT ?

I have seen some references to Mandriva 2009. But never used it.
