For gaming? Ditch virtualbox and migrate your VMs to libvirt/KVM/qemu. On my main PC I have an RTX2070 Super and a GTX 1070. I pass the RTX2070 Super through to a libvirt Windows VM and via Scream & looking-glass I can play any and all Windows games at full speed. Elite: Dangerous, No Mans Sky, and so on, run at full speed inside this VM. An alternative is to run a lot of games via WINE and/or Proton-via-Steam for Linux, which also works fine. Turns out Windows is basically a gaming OS these days for me - the rest of the work I do gets done on Linux. And lastly I think I'll be stopping at Windows 10. Running nice and snug in a VM.
