Or, much cheaper solution. Bootcamp it?
I played both and honestly it didn't do much for me. Although that's because I think that TressFX is still limited in the number of titles. Although I feel the same about PhysX these days.
Hopefully AMD push TressFX more, as apparently Feral can get it working on OSX if AMD just get support for the API on it.
I'm very fond of gaming in general, and I took a liking to OSX, and like gaming. Part of it is my old nature of fiddling with things. Instead of custom PC's, it's not games.
Although titles like Farming World ruin the experience, on both OSX, and Windows. Especially since it's a full release. :/
In the end, I believe Mac gaming is awesome, and getting better. I also think the same of Windows gaming, and while Linux is plottering about. It's certainly far ahead of what it was in 2012.
I think many people tend to forget there's far more out there, than just so called 'AAA' games, which are anything but AAA quality in regards to story, creativity, gameplay, and fun. * my humble opinion *
As such there's a myriad of games out there, and it's so hard to even notice all of them being released. Especially with the sheer amount of rubbish on Steam these days, everything from shovel ware, to companies simply slapping up old 90's games without even modifying them in anyway to work properly on newer systems.
In the end, as always I think people just need to find that system they prefer. Hell even if it's only playing Amiga games, as the prime and best. As long as you're having fun it's all A-Okay.
On a side note, once that lovely 4K display I want is back in stock I'll probably just try and game everything on that in native res.
