Hello, I just purchased a asus pg278qr 2k 144hz monitor but I may rma it to Amazon cause 165hz not working. I saw a nice aoc display at 4k 60hz with g sync for the same price so I was thinking of swapping. I got a gtx 1080 ti from asus and I7 6700k. Will the g sync make a good performance at 4k? I don't want low frame like a consolle, I'm not sure, can you help? Thank
