I would expect so, though are you planning to upgrade from an i7-7700K? To what, an i7-8700K?
Obviously that will help with some games since you have SLI GTX1080, though I'd be curious to know how MUCH it actually benefits.
If that's your plan I would also WAIT for a few months for:
a) motherboard review to come in with sufficient TIME to see what motherboards are solid and which ones have issues, and
b) BIOS updates
