Hello, currently my system has two 1080s in sli and im using a 4k60hz monitor which i love. Recently a stain appeared on the inside of my monitor so i am sending it back for a full refund. Should i get a 28" 4k 60hz acer predator with gsync up to 75hz refresh rate or should i get a 27" 1440p 144hz monitor? I love gaming at 4k and to be honest i have never tried or seen in person a 144hz monitor. when using my 4k monitor and trying 1440p it really looked console graphics for me, i dont if it is cuz im used to 4k. Any advice? Will i regret getting a 1440p monitor which is half the res of my 4k monitor or should i just get the 4k with gsync 75hz?
