I actually bought an RX 580 8 GB new for 139 EUR last year (most likely sat around some warehouse in an unopened box for years) - it has no issues running most indie games or even the decently optimized AAA games at 1080p, which was an upgrade over my previous RX 570 4 GB.

The only actual issues I ran into were when I tried running it for PCVR (Quest 2) because the latest drivers actually cause crashes and instability, although I could fix that by rolling back to either the 2020 or 2022 drivers: https://news.ycombinator.com/item?id=38870500

Sometimes hardware from generations ago is not only decently affordable, but also sufficient for what you want to do, as long as your standards aren't super high. Getting some of that hardware with no previous owners also feels a bit interesting, albeit I've also bought used CPUs off of AliExpress for my homelab servers with no issues either.

You can find used 1080ti's for like $100 nowadays. I still use one for 1440p gaming and get excellent frames with most games. Kinda mind blowing value
