Macs have sucked, do suck, and likely will suck for all time to come as far as gaming is concerned. They ship with shitty graphics cards, have bad cooling, and there's simply not much in the way of interest from Apple in supporting gaming.

If enough large games were released for OS X, even as a port, Apple may put a little more effort in. And yes, the graphics cards are weak (mine is an Intel HD 4000.) But look at the Mac Pro. They invested a ton on engineering it for performance, including a lot of effort on the cooling. Apple can do it, they just need a little push. And now is a great time for it, they have no place else to go. They can't keep marketing the CPU speed or how thin the machines are for much longer. They need a new metric to push and gaming performance would be a great one.

The only way Apple would become a good choice for PC gamers is if they started shipping computers that competed on price with gaming PCs while offering comparable performance.

I could easily see "casual" PC gamers (people who play games casually, not who play casual games) buying a Mac for their general purpose PC and playing games on the side, iff the Mac offered decent gaming performance (they don't) and were priced around the same as a decent gaming PC (they aren't).

It's a chicken-and-egg problem, though. Studios don't want to invest in making (or even porting) games for a non-gaming platform, gamers don't want to buy a computer they can't play games on, and Apple doesn't want to invest in pleasing a consumer segment that doesn't exist.
