^what he said.
While there are a few games that run quite will on my Surface Pro 2107 (i7/256) namely Space Pirate Trainer and Superhot. There's a thread on what WMR games will run on very low end hardware
here.
It all comes down to the graphics card (mostly) and it is an exceptionally crap time to be buying a standalone GPU with the inflated prices due to mining demands. Consider some pre-built desktops from HP/Asus/Dell (I can't believe I'm saying that!) with a minimum of a 1060 or greater. A 1070 or 1080 will be better of course and will look and play much nicer.
A small portable VR gaming rig? Well yes maybe, but not cheap. Check out something like
this which will serve you well.
Hope that helps,
