I'm running a 12600K and thinking about moving up to a 14700K or 14900K. I have more than enough PSU and cooling for even the 14900K and my motherboard supports up to 14th gen with updates to avoid cooking my CPU.
I'm just not super sure a few more cores a lot more cache and nearly flat base core speed is worth $500 (for the 14900)

I have 3080 so I don't have a sub $1500 GPU upgrade path.

I was wondering if anyone has done an upgrade from 12600 to a 14 series and how they felt about it.
The money isn't super hard for me I just don't want to be wasteful.
