You can set up different GUI Interfaces in Ubuntu.
For example if you don't like Unity Desktop in Ubuntu 16.04 LTS then you can install KDE Desktop. Or you can us Gnome.I am sure there are other options.
The LTS releases for Ubuntu are supported for 5 years.
I have looked at the latest AMDGPU-PRO drivers and they are running well for me on Ubuntu-16.04 LTS.
I am looking at setting up Virtual Machine with a Windows 7 installation as a secondary OS and then use GPU passthrough so I can run Windows based games using GPU Hardware.
Use of GPU Passthrough with Virtual machine is bound to become very easy to set up in future Linux Distributions.
There seems to be more and more people who have or want to move away from Windows 10 and on to Linux.
Linux dominates all other areas of computing now apart from the Desktop PC & Laptop for consumers.
I think it is time that Origin provide Linux ports for their games and provide an Origin Client that can run directly on Linux using Vulkan.
Personally I see no reason to stay with Windows as my Primary OS any more.
I move it to secondary OS inside virtual machine, for legacy reasons.
