Upgrade path assistance!

Hello all.. new to the group and glad to be here. I built a budget pc quite a few years back and have upgraded it over time, but it's possibly time for a new build, or mostly. That's where I need your help. When the next Gen cards come out, I plan to upgrade. My current monitor is 1440p 144hz which I really like for competitive games, but I may shoot for 4k, What I need opinions on is, is it time for me to upgrade to ddr5, meaning a new mobo and cpu? Or, am I fine with what I've got, just upgrade gpu? (I feel I may be held back, and I'd probably have to stick with 1440p?) Go easy on me, I don't know everything. thanks for your time!
