It's really up to your own preference, but if you're trying to future-proof your set up then 144Hz might be worth it. But if you don't play games like shooters (where refresh rate is important), then it might not be worth it for you.
Thanks for the help! :)
I decided to go with 60Hz 1440p but it is AH-IPS so I think it's going to be good!
Yeah that thing will be a beauty. I think you'll be very happy with it!! Enjoy! :)
