Thanks for the effort. I have a Clevo W650RC running Ubuntu 16, almost the same hardware as the author but with an extra gtx950m gpu. I own 4-5 Humble bundles and claimed all Steam keys, which makes installing those games, installable, playable and therefore recommendable. Sometimes I would run with the Intel gpu, and most of the games still ( I am pretty sure all of them) run, but of course much slower. I also bought an Steam controller and really like the setup, most games would pick up the button mapping. The only thing which sucks donkey balls at the moment is tearing under Nvidia + Linux, either in videos games, browser etc..- Also I want to add, that I own Serious Sam 3, Tomb Raider and Shadow Warrior, and I must say that the ports of these games is just top notch.
