I got a 75hz 1080p AOC monior around December 2017, and I am looking into getting a 144hz monitor for my gaming pc, but they are just so expensive. Idk if i should sell my AOC monitor and use that money towards the new monitor or if i should hold off on it alltogether. Btw the AOC monitor's model # is i2778vh. I got it from best buy for about 150 usd
