Was thinking abkut 1440p, so whats ur opinion on that ? 2560x1440 144hz ?
Now that entirely depends on what games you play
You mentioned Apex Legends:
you will have to turn down the details to get higher frame rates at 1440p with the 2060
not even the mighty rtx 2080Ti will able to give you constant 144fps
funny thing is that i also recently upgraded to a 1440p 144/165hz monitor and that is when I realized that I will really have to upgrade my gtx 1080 if I want to enjoy higher fps than 60fps when playing newer games like SoTTR, Far Cry 5 and Control
