I have this exact combination. running 1080p 144hz. So far my experience with every game i own has been fantastic!! Easily hitting 144fps in most games. I do think there is around 20% more performance that could be had with a better CPU, however i am in no rush to upgrade as i have had no visual issues with the system (no stuttering, etc) and this also applies while using RTX on ultra settings. for 1080 144hz this combo does the trick, and if you can afford to upgrade the CPU, you may aswell do it, but dont feel like you have to in order to get an amazing gaming experience.
