How much better are the Asus PG279Q (X34 etc) than monitors that are over 5 years old. I have a Dell u2711b that’s a 1440 that I got 2011/2012. I get a itch to upgrade but at over $1000 Canadian I am afraid I would only be making a sideways move. I don’t play FPS but Dirt Rally, Witcher 3 would be the most taxing games. I am running a 1080 video card.
