KVM pci passthrough on Asus G750JW

I have an Asus G750 with a 765m with Nvidia Optimus that I have installed Arch Linux onto. I am running the Intel drivers right now and was wondering If I could get the 765m passed to a Win7 vm. Would it be better to setup Bumblebee instead?

not really sure, check this guide: https://bbs.archlinux.org/viewtopic.php?id=162768
also check if your cpu supports vt d also check your motherboard
