Adding Video card to host to be used by the guest OS

Hello,

I have a system configured with ESXi 5.5 and i need to have the guest OS use the video card in the Host. The Host is a Sabertooth X79, the Video card is a Nvidia GT610 and I need to be able to access the GPU for graphics rendering. I have 5 VMs installed that will all be running graphics and i need to be able to use the GPU for all of them. Is there a way to do this?

Thanks
