Yes. A 1060 will support all 3 or you could keep the igpu enabled and use it to power 1 or both of the 1080p displays.
So what you're saying is that I can connect both 1080p monitors to the internal intel GPU of the Z170A and i can buy the GTX 1060 and connect my 4K TV to it?
Will all the monitors and 4K TV play content at 60HZ?
