Hi guys, I'm in the market for a new monitor. My current monitor is a msi optiplex 27 2500x1080@144hz. Its a good monitor but I would like to give 1440 or 4k a try. I don't know if thier is any real difference between 1440 and 4k. So what are you guy using? Ny budget is $300-$350. I would spend more but Im getting a trackir.

my system
geforce rtx 2070 super
16gb ram
windows 10
