I used Server 2012 with Hyper-V enabled on this very same machine, with no problem. Something changed in R2 because as soon as I enable it and reboot, my video card is no longer recognized, the 2nd display doesn't work and when I go to re-install the video drivers (nVidia Quadro 600), it can't find the card. I'm pretty sure that I called Microsoft or otherwise got definitive information from them that there was no fix for the problem, so that's when I decided to just use Virtual Box for my VM needs and that has been working out for me.
