So i am awaiting my new PC to come that i built from Cyber Power. On my old PC i was gaming on a AOC 60hz monitor. To be honest i did not notice anything from the monitor that was greatly affecting the performance it was fine for me and im not one to go out and buy a $400 monitor i mostly played CSGO Dota 2 and overwatch on it. But all im hearing is 60hz is crap and i need to be using a 120hz or 144hz or whatever. Will the Hz difference really affect performance? or is it more of a preference thing. Im planning on getting a second monitor anyways so im thinking about spending the extra money for a 120hz or a 144hz... is a really worth it?? because i when my PC comes im getting a new PSU for it and i dont want to be spending a ton of money on that and the monitor if a 60hz will do me fine.
