Upgrade Suggestions?

[Hodders]

Current system is:
MSI B450 Tomahawk Max
AMD Ryzen 7 3700X
2x8GB Corsair CMK16GX4M2A2400C14 Vengeance Ram
3070 GPU
500GB M.2 Sandisk G5 BICS4 SSD system drive
1TB M.2 WD WDS100T2B0A SSD games drive

Uses - it's my games machine (work is on a separate laptop), Currently play World of Tanks (can't stop ), AC Shadows, Last of Us 2

System is broadly fine for what I use if for, although my brother suggested for some more recent games 32GB ram would help.

What would you upgrade and in what order?

Or given the system is already a few years old, would you start saving for a whole system upgrade?

PSU is a Corsair RM850x

Budget is flexible - don't mind spending more for a better upgrade.

I've never bought the latest fastest - always one back - hence 3070 not the 3090.

Case is a decent size Corsair case with loads of space inside - PSU is at the bottom if that matters!

So looking at costs:
5700X - £140 - or - 5700X3D - £209 (is the extra cache really worth it?)
32GB 3600 Ram - £125 (Corsair vengeance 2x16) only £90 for 3200 ram.
5070 - £500 (£340 if I sold my 3070 for £160)

So it feels as though the best bang for the buck would probably be:
1) RAM
2) GPU
3) CPU

Thoughts?
