Bought the rMBP last year (maxed out memory and SSD) plus 2 Thunderbolt displays and a Thunderbolt external HDD, and it's been a great setup. However, my photography (Lightroom) and video (FCPX) workload is getting bigger and bigger. In a few months it'll double in size again. I spend at least an hour a day listening to the laptop's fans on full blast, and that's only going to increase. I'm thinking it's time to move to a Mac Pro. I don't expect that big of a speed increase, but I'm a little worried about wear & tear. Turns out I don't really care about portability - well lets say I'm much MORE concerned with a long lifespan, dirability and expandability, than I am with portability. Only downside is I'll need to get rid of a TB monitor (I can use one for a Mac Mini elsewhere in the house) and ext HDD, since those are useless with the Mac Pro. I'd be getting a refurb unit. Am I on the right track?
