What it is
A 2015 Linus Tech Tips build log showing how to run two gaming PCs from a single tower using virtualization (unRAID with GPU passthrough). Linus walks through the components and setup that let two players game simultaneously on one machine.

Yes, but importantly you need two graphics units of some sort or another. One for the Host and one for the Guest. Normally I wouldn't include videos in answers but Linus Tech Tips recently did a very concise video on how to run virtualized gaming. 1 System 2 players. The concept is the same for what you want.

as far as I can dig google and other stuff, ATM there is no working way to have any hardware passthrough (other than CPU) with Windows Host, even if on windows virtual box still got the option "--pciattach", any attempt to use that will make virtual machine crash while under Linux is working - 2 Gaming Rigs, 1 Tower - Virtualized Gaming Build Log [this video] (unraid is a special customized Linux just for that) let's hope this will change for the windows too, sometime soon ... hope die last ^^

You can set up a virtualized system but, like Seth suggested it won't be satisfactory and may require maintenance and 100% uptime is really doubtful, still if you want to go ahead go on reading You would have already figured out you need multiple peripherals for each of your virtualized Workstation. Which includes a mouse, keyboard, monitor etc. I'd suggest you to buy two more 'cheap' GPUs in addition to the 970, for your HOST OS and other two users, the user running off the first virtual machine gets the 970 for extra horsepower, in your case 3D rendering etc. Later two will run off the two additional GPUs. Host OS runs off the on-board CPU graphics. Sharing a single GPU in a virtualized en
