Monitors can be a little bit under-appreciated when it comes to upgrades and builds. The reality is, you are not getting the full experience and performance of your glowy graphics card unless it's on a 120Hz or 144Hz refresh rate monitor. A refresh rate of a display refers to the frequency at which the image is changed. Monitors like Acer Predator XB321HK and Acer Predator X35 are really a blessing for gamers.
