Hi! Thanks for your input.
My only understanding of 144hz(because I haven't seen or tried one) is that it looks much better and life-like(dunno the proper term) compared to a 1080 60hz monitor that I have. Well, I am okay without AA, A little bit of shadows maybe low, no idea of ambient occlusion though maybe i will test it soon enough.
From what I understand from your statement is that, Getting a higher refresh rate of a monitor will give it better visuals when for example playing csgo or watching fast paced racing cars? Sorry No idea.
