I have a 17 in alienware laptop with a 1070 and a it has a thunderbolt 3 port. I was curious if i had a thunderbolt 3 docking station could i game with my discrete graphics through thunderbolt 3 to the docking station to the hdmi to my monitor? i think i saw at somepoint that a docking station through thunderbolt 3 would just use my intel graphics not my discrete GPU. any help with resources would be appreciated.
