I currently have a RTX 2060 paired with i5 9600K on Asus Z390-F motherboard and a 2k monitor. I want to upgrade to a 7800 XT but I suspect I will be bottlenecked by my CPU. The obvious route is to upgrade my CPU as well but if I do I'll have to change my motherboard too because of different sockets which would put me way overbudget. So can anyone tell me how much of a bottleneck will my i5 cause at 1440p and if it's worth it to upgrade?
