My whole life I've been using a 60Hz monitor. For: Gaming, video editing, video VFX, programming...
But when my friend shared a link to this monitor I've realized that at that price, such specs are a STEAL!
When the monitor arrived, I was excited to try it out, to see if it will actually be such a big jump as people talk (Moving from 60Hz to 165Hz). And well... It's like day and night, a buttery smooth experience, especially for gaming, it sort of eliminates micro stuttering, screen tearing, and overall feeling of choppiness compared to when playing on 60Hz panel.
Also, if you're using more than one MSI product, like motherboard, cooler, etc, they have an app that controls everything, called: MSI Dragon center. With its current version (Current date: 2020.09.24) on my computer, it does something that starts to lag my mouse input. But that goes away once you exit the app (Closing in the taskbar/system tray). Just a heads up if anyone encounters that problem.
Overall, if you're looking for an upgrade for your old monitor and you want to use it mainly for gaming, this monitor is perfect for that. Although I would recommend having a bit wider table for that (Mine is ~50CM from chair to the wall and it's a bit tricky to have this monitor on such a table, thanks to its stand/feet sticking out to the front)
