With the MacPro this Config you can run pretty well anything without any issue, most RAM intensive is when doing anything with Video, but CS6 not a problem, I run several Applications at any one time, doesn't Phase the Beast.
The MacBook Pro this Config, runs CS6 without any problems, but it can slow a bit when doing anything with Video if your running say CS6 + FCP, as long as your running a single Application or at the most two, runs well.
