Best value upgrade for my setup

I'm a GPU poor, unlike the vast majority of you. I have finally secured funding, and would like to upgrade my rig.

At the moment, it consists of:

\- RTX 5060 Ti, 16 GB VRAM

\- 32 GB RAM

\- 2 TB NVME

Given the skyrocketing prices of everything, I'd rather not wait for Black Friday to come around. Last year, it brought the RAMpocalypse, and we've not yet recovered.

So, given this scenario, what would be the best value upgrade for this setup? I'd set the budget between $1000-3000. Make that euros, am in Europe.

I've considered:

\- 1/2 used 3090s

\- swapping the 5060 for:

\-- an Intel Arc B70

\-- a 7900 XTX

\-- a 4090 (5090's are now absurd)
