Anyway, I don't get the appeal of these for gaming on a Mac. For all the expense, you cannot even achieve maximal performance.
Why not spend the money on either a gaming laptop or desktop just for PC gaming instead? You get your Windows install included, whatever GPU you want and it really isn't that much more money is it?
This strikes me as a cool thing to do from a geek point of view just because you can rather than being all that practical or economical at this point.
The appeal is I can now play any game that has come out on my almost 6 year old 2012 Retina MBP. Could I have spent $600 on a Desktop PC and been able to do that, maybe (I don’t keep track of component prices or build prices). But I don’t want a desktop PC. And I want to be able to use a Mac as my main computer and to game on too. Now I have a 6 year old Mac that does everything great except game, and by spending $600 it games 3x better than the newest $3000 MBP. That is a bigger appeal than almost anything that has happened gaming related to Mac since the switch to Intel 12 years ago
