Been using CS6 PPro since I downloaded trial earlier. Vast improvement on CS5 for me on my Mac Pro Mid 2010 12GB Ram 2.8Ghz OSX 10.7.3.
Love the fact the work area can be disabled and I can select and render in to out for more complicated fx laden sections. Performance is excellent on my Mac Pro so far and have not had to render much at all.
Copied my BorisFX Red and NewBlue fx plugins to CS6 package contents. Installed Magic Bullet Suite (Thanks to swift action by Redgiantsoftware). Plugins are working well so far.
Like the new interface. Can't check out Encore until May 11.
So thanks to the development team.
