Is the difference between 2m and 6m very noticeable for games like CS:GO? I have the choice of getting an Asus vs248h-p or a Dell S2415h. Asus has a 2ms response time and the Dell has 6ms. I really want the Dell because of the thin bezel and it looks really sexy. I want to know if the 4 ms difference make a really big impact on CS:GO.
