I know most people here are probably running 120+hz monitors at this point, but for anyone still on 60....
I recently bought a Dell G7 laptop with a 60hz display, so that I could have something to play games with at my fiance's place and work. My intention was to hook it up to my 144hz monitor at her place, but quickly realized the laptop only had a miniDP output and the monitor only has a DP input. I wasnt able to find a miniDP to DP cable locally, so I have been running at 60hz in the meantime.
I figured the difference in a game like DotA wouldnt be that bad, but dear God going back to 60hz is soooo jarring. I know Im stating the obvious that better tech is obviously better, but man the performance results are so much more obvious when you go backwards rather than forwards.
TLDR if you are still running 60hz monitors, stop.
