Hi, I'm planning to build a PC with a motherboard with thunderbolt 3, a 6700k and a GTX 1070. The thing is I want to hook up this PC to a Apple Thunderbolt Display, and I've found that StarTech.com Thunderbolt 3 to Thunderbolt adapter, which is an adapter that does exactly that. If I were to connect the ATD to this adapter through the thunderbolt adapter to the thunderbolt 3 port of the motherboard, who would handle the graphics processing, the gtx 1070 or the onboard graphics of the 6700k? Is there any way to force the 1070 to handle the graphics? (Sorry for bad English)
