Advice on upgrading parts

I have a :

msi h310m pro-vdh plus

24 GB Ram

550w PSU

RTX 3060

I7-8086k

————————————

I originally made this pc back in 2019 and upgraded it through the years. A few months ago I changed the i5-9th gen to a i7-8086k. But it’s showing it age and plus it doesn’t have m.2.

So if I were to upgrade ; most likely the psu mobo and cpu . I don’t know if I can keep the ram and if psu would be good enough to keep also if my gpu is good for a few more years . I’m thinking of the intel core ultras or going amd. I don’t want it to be like super expensive as long as I can play modern games on high settings .

Any advice would be good thank you 🙏.
