GPU PCI pass-through virtual machine with no GPU in CPU?

[pertplus]

I'm looking for a VM that will allow me to use PCI passthru and kernel virtualization. My CPU is the intel i5 760, which does support intel virtualization technology. I want to use PCI passthrough for my GPU, nvidia geforce gtx 650 ti.

However, my processor doesn't have a build in GPU. So is it even possible to have a virtual machine use pci pass through to access the nvidia GPU, while still making it available to linux?

So my first question is, is it even theoretically possible with my set up? I just want Win7 in a virutal machine with full or close to full graphics capabilities.

If it is possible, my second question would be, what's the best vm software to use. Right now I have Virtualbox but it doens't appear to support any pci pass through.

If it's not possible, I'll probably just try WINE. But I like having a virutal machine, it's nice to keep windows segregated

thank you in advance for replies

I think what you want is "Primary VGA passthrough". XEN already supports it.
AFAIK, there's no technical obstacle for this function to be implemented in other VM, but only no one is doing it.
This function would be powerful, there's no way for WINE to compete with it.
