[PlanetCCRMA] GUI Issues with Dell Vostro

I have tried both Fedora 15 and 16 and discovered Gnome 3. Very sad for 
Linux. After 12 years as a user and staunch supporter of Red Hat/Fedora 
I have no choice but to move on. I find Gnome 3 simply unusable.

What would be the best alternative Linux distro to use with the Planet 
CCRMA suite of applications (principally Jack, Ardour, Rosegarden, 
QSynth and Hydrogen)?
