Yeah I ran into that wall 2 weeks ago. I tried to switch to Linux for the host and run my Windows 8 VMs in VMWare on Mint. After fighting with the nvidia drivers at install for a bit I got it working but VMWare using dual monitors is super slow on nvidia (780 here) in mint: the windows in the guest VM were drawn as if it was done by a single core on half the speed, instead of on the GPU. Single monitor, no problem.

Had to roll back to windows for the host to make the VMs work nicely. A bummer, considering moving away from Windows takes that first step and I now have to stick around for longer. Perhaps next year...
