Windows boot camp question.

hi,

I was wondering weather using Windows on a Mac through boot camp causes any disadvantages for gaming, as apposed to a native Windows PC.
I wrote another thread last week about which video card to buy for my 5.1 Mac Pro, and got some great responses and have a fair few viable options; however, concerns were raised, understandably, about OSX as a gaming platform.

For this reason I'd be going the boot camp rout, but I was wondering weather there's anything I need to know before I do that...
