There's a reason smartphone manufacturers are putting 160Hz screens in phones that are primarily used for viewing HTML. It makes a massive difference even in 2D content like little flat circles going down or just your cursor moving around.
You can show a 60Hz screen and a 120Hz screen to someone who has zero knowledge about tech, have them surf the web for a few mins on both, and they'll tell you that the 120Hz monitor felt smoother and more responsive, because it was, and it was twice as smooth as responsive, so even a cracked out retard like Austin could tell that the virtual pachinko feels smoother.
