Has anyone of you used both? I just installed trial of the CC and it runs noticeably slower than the 5.6 on my Macbook. It's a 2.3GHZ i7 with 16GB RAM so the computer definitely is not at fault.
Odd. I found CC generally runs very nicely on MBP aged 5 now. (Just like Adobe claimed on the tin.)
Might be worth looking under the hood a bit - scratch discs and techie stuff. Someone who attchoolie nose wot they're talking about may be along in a minute....
