How to install games on OpenSUSE Factory?

Hey there! I am new to the forum so please excuse me if I have got this in the wrong place or its already been answered.

So later today I am moving to Linux on my main gaming system, and I hear Factory allows for a bleeding edge yet stable environment, which I have been looking for since fedora screwed up the AMD drivers, and I would like some advice on playing games on Linux.

I know there is Wine, but how far behind main-stream wine is PoL? and whats it like for stuff like Diablo 3 and borderlands 2?
Also I am tempted to run a QEMU-KVM setup for Windows specific stuff, hows that working in openSUSE and what performance may I be getting?

Thanks!
