Finally I have everything running on CentOS 7, latest kernel, nvidia driver, steam and all my development tools. So now I'm up and running on that.
Very happy with my setup.
Was a pain in the ass to get everything working, but now I have a script that does most of it. so that feels great.
Only thing now I do not have installed yet is the cuda libraries so that I can compile blender with GPU support, I'll do that this weekend. Also I need to get playonlinux up and running with wine staging so that I can play some of my windows-only games on there too.
