What should I upgrade

Hey, I'm looking to do some minor upgrades to my PC to get more consistent framerates on newer games. I'm using a Ryzen 7 3700x, 16GB DDR4 RAM and an RTX 3070. Which one of these parts should I upgrade if any, I'm not too bothered if they're all still good for now and I should wait to upgrade, but if I were to do it now what should I change?
