SLI Laptop + VT-d = windows guest gaming?

[statikregimen]

Greetings!

Just wanted to do a quick sanity check before I drop $1800 on a laptop upgrade.

Currently, I have an MSI GT72S with a single GTX980M 8gb GPU

I'm looking to grab a nearly identical model but that has dual 980M GPUs in SLI, with the goal being to dedicate one of the GPUs to a virtual machine running Windows to fill in the gaming gap. I've tried Steam in-home streaming, but just not getting great results (gigabit LAN, but still loads of input lag, and other annoyances like some/all games wont use my joystick or controller, resolution issues, etc).

I did confirm that my BIOS supports VT-d so I have no reason to suspect the upgraded laptop wouldn't also. I believe that is all I need for this sort of thing? Will the SLI bridge cause me any headaches (and i have no idea how the bridge would be made or if i can physically remove it in a laptop or if it'd be soldered into he motherboard)?

Any other pitfalls with this sort of setup I may not be aware of? I've googled it and it seems like once it's set up most people find success, but I may be missing something still.

Any insight is hugely appreciated.

Thanks!

Do you really want to have a SLI system?
