I had been wanting to do hackintosh for a while, and after many failed attempts decided it wasn't worth the trouble. I'm now looking into getting a Mac Pro. I don't want to spend $2500 and be stuck with anemic graphics cards, so the nMP is out of the question for me. I'm looking at getting a Mac Pro, preferably a 5,1 I'm thinking just to keep it current for the longest amount of time. Anything I should specifically look for when buying one, or is there a specific model that seems to be the sweet spot right now in terms of getting one used for a good price vs. its performance? I'm thinking I'll add in a GTX 980 GPU, along with running Yosemite. I realize I won't get USB 3.0, but I'm not really using anything that needs it. Any tips or advice would be appreciated. I mainly use my computer for casual use and gaming (all my games are Mac compatible).
