I use Parallels Desktop with Windows 7 right now. The game runs just fine and Parallels supports dual monitors. If you run it full screen you'd have a tough time telling that you weren't sitting at a PC instead of a Mac. Since the processors have been the same for a while, performance is quite good. It will cost a few bucks. I believe Parallels is about $50, but the real cost is needing a copy of Windows to install. But I had it anyway as I use Parallels for scientific computing applications as well.
