I thought he wanted gaming in OS X. Gaming in Windows is pretty well established. The first 2 links are down, by the way.
Well only one of those videos iw Windows, ALL the rest of them are games and benchmarks ran under OSX. Exactly what the OP wanted. So you obviously watched them before posting a reply then?
I'm not sure the exact pricing of steambox, but you can build your own gaming PC for the price of a PS4 which will have better hardware. You could even install the free SteamOS on it. Go on youtube and look for "kill your console." The PS4 is not an especially good deal on hardware.
Not even going to bother to honour you with a reply on that garbage! Wrong thread for that, go and post a thread in the Console section or Mac Gaming section if you want to argue it out.
