The new Asus PG278Q 27in/144hz/IPS /G-sync/1440p is the ONLY choice you should consider for monitors in the 600-1000$ range FOR GAMING. The others simply do not compare. (Unless you're running minimum 2x Titan Xs or 2x 980's and can afford a really nice 4k monitor, but even then you're still only gonna get 60hz which means 60 FPS maximum. PC hardware isn't quite there for 4k)
