Depends what you want and what your budget is.
There is a list of supported cpus somewhere but it basically means for official win11 support you would be looking for intel 8th gen or newer and if you are an amd fan ryzen 2nd gen or newer. Need ram as well because they take ddr4.
Could probably get a decent cpu/mobo/ram for about £120 that is much better than your current system and has win11 support.
for example:
i5-8400 £30 at cex . 2x8gb ddr4 £36 at cex.
Plus either h310 mobo for £35-40 or for more connections if needed a b365 motherboard is £55-60 which you can find on auction sites.
similar for amd stuff.
Then in about three/four years the current 13th gen will be available second hand reasonably.
