CPU/Ram upgrade worth it?

Hey guys..!

So I'm trying to decide if an upgrade is worth it. I know I probably don't "need" one, but just wanted to see everyone's thoughts.

Currently have: CPU: Intel Core i9-10900k @ 5.0Ghz (86SP I think)

Mobo: ASUS Z590 ROG Hero XIII

Ram: Corsair Vengeance RGB Pro 32GB 4000Mhz

GPU: Asus TUF OC 4080

Cooling: Corsair H150i ELITE CAPELLIX 360mm RGB Water Cooling

PSU: Corsair HX1200

Would an upgrade for my CPU be worth it to also be going with DDR5 or would I not notice a huge difference?
