Ok - copy your problem.
Changing your platform for gaming alone is surely not worth it - that is why I have made a desicion of principle to stick with games that run on PC - I think you will come to a point in your life where a PC will come handy.
While bying a PC for this reason alone would be a bit wasteful, you might want to consider the fact that PC is a standard tool in work and study ... with the added benefit of games of course.
I am actaully a Mac fancier - and I am running Win XP on my Mac just to be able to do some gaming. So it could be worse - you might have a bastardized operating system on your HW!
