Test the performance of GPU passthrough to a Windows Virtual Machine, so that Linux gamers can have the best of both worlds.
So, one GPU for Linux (host), and a separate GPU for the Windows VM. Could try mixing up AMD and Nvidia cards, etc etc.
The goal here is to find if there's a significant drop in performance between dual booting, and GPU passthrough.
