Anyone using a 2013 MacPro?

Would love to hear comments on the new MacPro from anyone who has made the leap (I’m sure there’s a few out there)

Have you noticed any big improvements in performance using CB 7.5? What are the specs in your new system and old system? I have heard one guy on the net say they smoke when you’re video rendering which makes sense given the dual video cards, but for most other operations there wasn’t much of a difference.

Comments from 1st hand users?
