Yup. My gaming PC is still rocking a 3700X and an RX580 because finding stock for GPUs at close to MSRP for the high-ish or even mid range cards is near impossible. :(
Edit: and I’m in Germany which means import fees, and other things that make things a bit more expensive.
I've basically in the same situation as you - same specs, based in central europe - and the GPU situation is dire. PC components places here are completely wiped out of GPUs. The RX580 is gonna be fine-ish for me for the next wee while, but I'd like an upgrade if possible.
In Austria even 1660s are >400 Euros. Try that for insane.
1080TI was one of nvidia's "mistakes" as it was ahead of its time in performance and VRAM size and was one of the reasons people owning it could afford to skip the overpriced RTX20X0 series and even the RTX30X0 series. That's why they held up in value so well, even before the pandemic shortages.
