Today I got an Acer (XG270HU) after having a 4k monitor for a while. I tried it out some and the performance test on straight ultra says 120fps (with a gtx 1080 and ryzen 7). Unfortunately I couldn't get a great test because I sliced open tip of my W finger pretty good earlier.
It's not gsync but after a round I didn't see any issues at all.
