Two great Gigabyte gaming monitors paint fast, crisp, and colorful pixels at all-time low prices — your choice of a 1440p 240Hz or a 4K 144Hz model

If your thinking of the 240Hz monitor just make sure you have the hardware to make it happen. I use a 7800XT and I had to lower settings on games way down and adjust resolution to get close to 240Hz on any games.
I will say I could FEEL the difference though. Not as much as going from 60 to 120 felt but it was there.
(If you don't know the feeling try checking your phone and see if it has a choice between 60 and 120 refresh rate. Switch between the two and scroll the screen around.)
