With Surface Books, does the GPU make a huge difference compared to the integrated graphics?

With similarly spec'd Surface Books, with the same processor and RAM, does the GPU option make a huge difference in performance, compared to CPU powered graphics? And would the GPU option make a difference in CPU heat, since the CPU doesn't have to handle graphics as well as everything else it's doing?

It can do, really depends on what you choose to use it for.

Generally yes, but as stated if you're just browsing your email it wont affect anything.
