Anyone know if this will allow GPU-passthrough of the Nvidia GPU? It seems to have most of the requirments

GPU passthrough requires a hardware video output for the discrete GPU. You can go looking through the moaning of Oculus Rift users[1] as they prowl laptops that do this, but it's pretty much unheard of in current standard laptops.
[1] Rift needs better video latency than you get with routing the DGPU output through the IGPU. Apparently there are now some specialized 17" gaming laptops that support a "direct mode" that might allow GPU passthrough to HDMI given software support.

NotebookCheck folks do some of the most thorough testing of notebooks you can find anywhere.

[1] For example: ArsTechnica review seem to have botched graphics tests somehow.
Having Nvidia GTX 960M GPU is a big part of XPS 15 value proposition (and what makes it stand out from e.g. Macbook Pro).
This doesn't show up in ArsTechnica review, yet it is completely obvious in NotebookCheck one.
