Things are better than you think ...
Apple doesn't really make laptops that cater to gamers and most gamers despise Apple.
A couple of years ago that may have been the case but things are (thankfully) different nowadays. The 8600M GT that appeared in the MBP last year was a decent card for a laptop and many people, including myself, had no problems playing games on it.
If you looked at similar price and spec PC laptops at the time the MBP's card compared very well and most of the time was the same one used by PC manufacturers. But Apple's laptop looked better and was thinner! Only really high end gaming laptops had better or SLI cards. But they were much more expensive, far louder and vastly thicker.
Even the last, white iMac had a decent graphics card option with the 7600 GT high end option and gave impressive benchmarks for an all in one, virtually silent desktop. It was only when the Aluminium iMacs were first released that people were disappointed with Apple's new graphics choice. But now thankfully they've picked up the ball again and added the 8800 GS as an option.
It's pretty tempting I tell ya, but I'm waiting for a (hopefully) redesigned MBP in June and want to see which graphics card they decide to put in there before making my next purchase. Speaking of which I'm still waiting for Barefeats to benchmark the new iMac's graphics performance and am looking forward to an impressive increase.
Of course you can't forget the Mac Pro which competes very well with PC's for gaming. You can add any Windows graphics card in there (as well as SLI) and play games in Bootcamp, where thanks to more up to date drivers, you'd get a better experience than on Mac OS anyway.
So, my friend, things are better than you think. Apple are far better with their specs nowadays if you're a gamer and own a MBP and hopefully they won't stray too far behind the competition in the future ...
