Hi Andy Z 03, thanks for your fast reply. I had considered the Mac Pro, but the i7 5K iMac has a faster CPU (compared to the quad core Mac Pro), and, from what I've heard, the upgraded GPU is equivalent to a single D500. And, of course, you get a 5K display with the iMac, which would add a significant chunk to the already very expensive Mac Pro.
Given how quickly the price rises when upgrading the Mac Pro (especially the 6 Core option with Dual D500 or D700), I think the top of the line 5K iMac is better suited for my budget. Now, knowing that the Mac Pro seems a bit steep, do you think the iMac will be able to handle the work described above?
To add some context to the budget situation, I'm a student, about to start my final year, so my budget is somewhat limited. But then if the Mac Pro will outlast the iMac, I guess it will be the wiser choice in the long run (even if it is more expensive).
Salspix, thanks for your insight. I upgraded to Yosemite when it was released, and have been very wary of Photos (haven't touched it). My library is backed up with Time Machine, so if Photos decides to convert my libraries, I can always restore the Aperture Version. Thanks for the warning though, I will be careful.
Thanks
