well, it's fundamental for my business, GPU overpriced can affect people's life.

I just want to upgrade my 9 year old pc. I’m not looking forward to spending $400 for what should cost $170

Contact local small-scale computer repair shops.

We often have used GPU's for around the price range you're looking for. They won't be fantastic, but probably an upgrade for a 9 year old machine.

Edit: I should also add, a lot of the really small scale shops also don't list 100% of their inventory online, with the benefit that it doesn't get scalped up like everything else.

GPUs are essential for a few jobs that are essential to our society. They're not just for games.

We must have different definitions of "essential". I'm curious which jobs you're referring to, because to my understanding, every aspect of society that I consider essential, has existed since before the advent of GPUs.

Modern computers have allowed these 'forever existing' technologies to scale to our population growth. Try building freeways without modern computers, or performing modern medical interventions without them.

I'm guessing CAD and engineering uses?

CAD doesn't really use GPU power, only a basic viewport that any integrated potato can render. Related simulation stuff (CFD, FEM) can be done with GPU compute but it seems that CPU is usually good enough.

Probably the most critical usage of GPUs is scientific simulations for biology/medicine, climate, space, etc.
