Microsoft 13.5" Surface Book 256G 2-in-1 Laptop

Does this have the discrete GPU? Looks like some best buy descriptions say yes, but the woot description does not…

This one will definitely not have that. This is the older model SurfaceBook which is now replaced by the Surface2 and Surface Pro and other variations.

But Microsoft had several variations of the original SurfaceBook; apparently one of the top-end ones did have discrete graphics. Most, like this one, has the built-in Intel 520 generation graphics. It does have mini-DP output to connect to displays or TVs. The Surface2 uses Intel 530, but not much difference.

From Microsoft spec for the SurfaceBook:
*Graphics *
Surface Book: i5: Intel® HD graphics 520; i5/i7: NVIDIA® GeForce® dGPU with 1GB GDDR5 memory

Surface Book with Performance Base: i7: NVIDIA® GeForce® GTX 965M 2GB GPU

That question is fully answered on the SPEC tab.
