Second hand AMD GPU's are selling cheaper than their Nvidia counterparts with same performance.
Lower level GPU refuse to go below 100€ though. Cards like the RX 580 or the GTX 1060 should be going for 50-80€ or so.
Last week I bought an RTX 2080 for 280€. I saw them going for 400-ish all the time and 280€ from someone at 40km was just too good to pass up, for that moment in time.
What cemented this decision was that it wasn't even a mining GPU, but it came from a 4K gamer.
Hopefully I can flip the PC quickly enough, before 280€ becomes standard.
And that 12GB 4080 is a 4070 at best, maybe even a 4060 Ti. Crazy (scammy!) that they're classifying it "4080" with such large cuts to shader cores and bandwidth. And weirdly enough, looks like the 4090 is decent value this time.
