Linux will never make it as a replacement for Windows on the Desktop, let alone as a gaming machine, lol, give me a break, Linux sucks for gaming, always has, always will.
There is a reason software/hardware manufacturers/developers in the main do not support Linux, and that reason isn't going away anytime soon.
I used Linux for a number of years, the best thing I ever done was get out of that Linux induced mentality, get away from the Linux Zealots, get away from Linux, and use an OS that CAN actually do EVERYTHING I want to do, and do it with ease, something which Linux, unfortunately, can not do, and probably never will.
