To make matters worse, the RTX3090 was released during the crypto craze and so a decent amount of the second hand market could contain overused GPUs that won’t last long, even if 3xxx to 4xxx performance difference is not that high, I would avoid the 3xxx series totally for resell value.

I bought 2 ex mining 3090s ~3 years ago. They’re in an always on pc that I remote into. Haven’t had a problem. If there was mass failures of gpus due to mining I would expect to have heard more about it

I have rig of 7 3090s that I bought from crypto bros, they are lasting quite alright and have been chugging along fine for the last 2 years. GPUs are electronic devices not mechanical devices, they rarely blow up.

How do you have a rig that fits that many cards?? those things take 3 slots apiece.

Pictures, or it never happened! :D

		you get a motherboard designed for the purpose (many pcie slots) and a case (usually open frame) that holds that many cards. riser cables are used so every card doesnt plug directly into the motherboard

I've noticed on ebay there are a lot of 3090s for sale that seem to have rusted or corroded heatsinks. I actually can't recall seeing this with used GPUs before but maybe I just haven't paying attention. Does this have to do with running them flat out in a basement or something?
