Question: is the gtx 1060 4k?
Answer: Yes, if support is all you want, you can do 4K gaming from gtx 1060 6GB. Infact the 1050ti supports 4k resolution. But having playable fps is a different story, you will be doing 20–30 fps at high settings in most games. You need a 1080ti for 4k gaming and even that fails to produce constant 60 fps.
