Question: can gtx 1660 ti run 4k?
Answer: The GTX 1660 Ti may have some of the features found in newer RTX cards, but it's still in between the GTX 1060 and GTX 1070 in terms of raw performance, making it unsuitable for 4K gaming. To enjoy games at 4K resolution, you'll want to spend the big bucks and look at the RTX 2080 or RTX 2080 Ti.
