Difference between 60 and 144Hz:
140%
From 60 to 165Hz:
175%
Even though 144 to 165 is only 14.5% increase.
It depends on what you're upgrading from and what your budget is imho.
When is OVERCLOCKERS getting Acer Predator XB273U GX 27" 270hz or Acer Predator xb32u gx 32" 270hz monitor????
I'm sure upgrading from 60hz or even 144hz these will be noticeable in games that you can push this fast anyways
Linus did a good video with pro gamers on this subject https://www.youtube.com/watch?v=OX31kZbAXsA
Acer supply is pretty patchy at the moment so I don't know.
We've got 360Hz Asus Monitors.
That is a great video!
