You need to give an idea of how much you want to spend
For Processors i think the I5 9600K is a nice upgrade
For GPUs I seriously recommend listening to Mr Simon Ross for the 3070. Unless you find a 2080 for less than £300 (I found my 2080 super for £300 second hand).
Could optionally upgrade your SSD.
I mean your builds still good, it really depends on what you want. If you want to play Arma and 90% of games out there, what you have is completely fine and doesn't need an upgrade.
If you want to play Microsoft's Flight Sim, Star Citizen ect then sure, upgrade. Your card and CPU will work perfectly on basically everything, give or take
