First time poster just looking for some advice or recommendations, all advice is welcome as I'm not new or completely unaware when it comes to building, but I'm also by no means an expert and the knowledge I did have is probably a bit outdated now too.

I custom built my PC back in February 2020, cost around €700 at the time for the MB, CPU, GPU, RAM, PS, and Case. Lasted me well but wasn't gaming for a while and now that I have the itch again and trying to play more, I'm finding things are running a little slower and am not able to play some games at max (or sometimes even medium) settings anymore. Windows also told me that my PC wasn't even compatible for a Windows 11 upgrade apparently :')

(CPU Cooler is the AMD Wraith Spire Cooler that came with the CPU, it just wasn't an option to add on PCPP)

I'd like to be able to comfortably play most games again, save for big AAA story-driven type games, as that's the kind of thing I prefer to play on the couch on console anyway. I don't have a massive budget but my birthday is coming up so I'm thinking about using it as a birthday present excuse from partner/family. Also I'm based in Ireland so I think places to purchase parts from could be a little awkward.

So if you were to upgrade my PC with all that in mind, what's the first thing you'd do? And what would be your full upgrade choices?
