I am in need of a replacement for my old desktop. While the desktop won't be a gaming computer per-say, I do want it to run specifically two graphically demanding games, the next Doom and Unreal Tournament (as well as development in Unreal Engine 4). The rest of my uses will be various work related assignments that so far have been, with some challenge (its a small and older macbook), satisfied by my laptop. I'm having difficult time coming to a conclusion, and would like to get some recommendations and advice from everyones experiences and expertise. These are the options I have thought of. Custom PC: I know the usual suggestion is to build a custom PC. While that I love the idea of customizing and upgrading the computer, I despise windows and the computer would be used ONLY for the games really. I simply cannot use windows for day to day or work. Hackintosh: Benefits of a PC with osx, but what about stability? Most of my time will be spent in osx, and it is crucial to me that it performs completely stable and fluently in it. I am concerned that this will be lost in the hackintosh as they are quite literally a hack job. There is also a concern over if I would even be successful in setting it up etc... I'm also generally not a fan of "non-genuine", though at a low enough price forget it. Fully loaded iMac: Extremely expensive and there are concerns over the performance of the hardware. I have always had and loved using iMacs, however at the price with no certainty of the performance of the 780M, I am uneasy that it may not satisfy my needs in the end. Of all directions though I am leaning in this direction if it can meet my needs, despite the high cost. Old Mac Pro: From what I understand some of the older Mac Pros have CPU's that rival or surpass i7's. On top of that they allow customization of GPU's etc... However I have had difficulty in figuring out which ones would be comparable for my needs, where to find them, which allow what customizations etc... It has been somewhat of a mess to figure which would be ideal, though I fully remain open to the idea. I had read you can get fully loaded iMac power for a lot less and still have a Mac this way, however it hasn't been so simple to verify and find such a case. Thank you.
