I'm not knocking Alienware or gaming in general, just pointing out to the OP that Alienware isn't what it used to be and there are probably better gaming platforms to use as references.

If you can afford a Mac Pro, you can afford a few hundred to put a GTX 680 in it and then it games beautifully.The mac pro you could, kind of, the new mac pro whatever.
Crossfired FirePros under Bootcamp are faster anyway.
apple doesn't hate gamers at all, the just don't give a **** about gamers on OS X.
and there's no 'kinda' about gaming on the 2012 and earlier pros- they run windows just fine, and I'm perfectly happy with the game performance I get from my 2008 octo under windows with an nvidia 680.
it's just not the cheapest way to get that done is all.
Apple hates gaming because gaming is a stupid waste of time that kills corporations.
Apple Loves gamers because game production houses buy bucket loads of Mac's. Well they use to.
Why would they buy apple over this? There's zero reason for apple to compete, just like there's not a Ford boat or motorcycle.
