Having a good dpi in gaming is very important , even more important when you are play ahooting fames like call if duty and gta 5 or cs go . Moving to the topic 800 dpi is the standard or as you call it normal . The key to having best aim is to use good guns and focus at the target and at the same time ...relax . When you have good driving skills you will have good shooting skills , idk if they are connected but they are for me . Go for 800 -1000 dpi
