Gamers would have heard and seen professional players in tournaments using 144Hz monitors to play Counterstrike and Dota 2. Now 144Hz monitors are really good but also means your graphic card should be able to make 144 FPS or more to make use of the monitors refresh rate. Investing a big amount on expensive monitors and expensive cards to run games at good quality settings is not worth it for most casual gamers. This is why we overclock monitor to get a huge gain in smooth game play.
Basics about monitors and refresh rates
Most monitors have a 60Hz refresh rate. This means that it can show 60 FPS. Now many gamers think that oh look CS:Go shows me 100 or 200 FPS. Well what is the point ? When your monitor can show only 60 FPS due to its 60Hz refresh rate and your graphic card produces 100 or more fps what happens ? It takes 60 frames from the 100 or 200 FPS and drops the other. This causes screen tearing, noticeable when turning fast. Hence it is recommended to either enable V-Sync or limit the FPS in games to the refresh rate of the monitor. V-Sync should be enabled only if your graphics card can consistently produce more FPS than refresh rate.
