So I decided not to go with Hyper-V.

After reading several sites trying to do what I am and having less than stellar performance I went back to Xen.
Amazingly Citrix completely opened up Xen and even made VGA Passthrough easy as anything else.

I’ve already tested with Xen on my main gaming rig and was successful in getting it to go through my main graphics card and display on at least one monitor.
Next step it both monitors, pass through USB for my devices, and test game and benchmark performance pitting my current Windows 8.1 rig against a virtual Windows 7. If it’s within a few percentage points I’m all in!
