Higher refresh rate does make a noticeable difference, if you have 60hz and 120hz or higher side by side you notice it instantly from the mouse cursor movement and scrolling websites etc, it's just buttery in comparison. Definitely not a must, just nice to have. I don't see the benefit of going higher than 1440p or 1600p though, any higher res just means I need to increase scaling otherwise things are too small to read comfortably for me.
