I am looking at getting a Mac and am not liking the Macbook pro or iMac setups. I need something good enough to process D800e photos as well as use FCPX for 1080p (and potentially in future 4k) editing. The thing is the base model mac pro is at the limit of my budget. It's good that the RAM and storage are upgradeable which I'll do over time as needed but I'm wondering if the 4 core + D300 setup is good enough? Is it a waste to spend all that much on a mac pro and only get the lowest model or should it still kick ass?
