Hi guys!

I'm a noob when it comes to other platforms, so I need help figuring this out. Basically, I own a iMac and I would like to be able to play Steam games which are only available for Windows users. I'm looking for a way to install some sort of Windows platform on my Mac without it slowing down too much. My Mac is quite new and has a lot of available space, so I'm looking for the best option.

How should I process to make this work?

Thanks!
