As one example take a peek at /r/LocalLLaMA[0] (I suspect you know). These people are snapping up anything and everything they can get their hands on at a reasonable price.

To your point on the P40, it's an eight year old card but fortunately Nvidia has a history of long term support (especially for "datacenter" GPUs). The Pascal series is still fully supported by the latest Nvidia driver and CUDA releases, and projects like llama.cpp are still fairly regularly adding performance optimizations for even Maxwell series GPUs!

Current V100/A100/H100/etc hardware families are not going to end up as e-waste anytime soon. In fact, compare used pricing (and demand) of GPUs to CPUs, RAM, disk, motherboards, etc from eight years ago... That hardware ends up in the trash/at e-waste recyclers much, much sooner (even with /r/homelab).
