I have a dell g3 I want to upgrade the screen for. I found this 120 hz screen that should be a decent upgrade from my 60 hz screen especially for overwatch. This is the screen: https://www.amazon.com/dp/B07CWSWX4Q/?coliid=IVN2UJDMMOQM1&colid=PR0IV7QF0WUF&psc=0. And heres the tutorial Im gonna use: https://www.youtube.com/watch?v=qXy2Q3vr9J4. Is this a good idea?
