Is there a reverse bootcamp program?

So I'm looking to get a laptop for mostly schoolwork, movies, social media, etc. but I'm also going to be using it for gaming. Mostly Indie, online and others like assassins creed and others. I found one I like and it's design is beautiful and is pretty decently priced (it's the Razer Blade Pro if that would help). The only thing I don't like is it runs on Windows 8. I LOVE the Mac OS so much better than PC and I would just get a Mac, but I just don't know how well they work on next gen games and other things, so here are my questions. How high of graphics and intensity of games can Macs handle. And I know you can run Windows on Macs through Bootcamp so is there a program that you can use on PC to run Mac OS?
