Windows 7

Dont believe WIn7 meme. If you don't want to upgrade to Win10, use Win8.1 instead. It is a great system and absolutely better than 7.

Windows 10™ is the perfect OS to suit your gaming experience. Update before July 29th and receive Windows 10™ for free!

If your only requirement is gaymen, W10 (unless there's some compatibility stuff I haven't heard about)

dx12 will be more widespread eventually, and there's already exclusives coming (recore, forza 3, gears)

if you're allergic to giving all your info to M$, you can just pirate W7

if you want to, you can just dual boot like I do

Whatever works.

Personally, I use GNU+Linux.

Every Linux distro out there
