that's a wild theory. You think there are really warehouses of GPUs that they are just sitting on until data centers are built, that will just all of a sudden flood the market?
First, the form factor of GPUs in data centers aren't the same as desktop GPUs, so you couldn't use them even if you wanted to in a normal rig.
Second, from a business perspective that doesn't make a lot of sense. It's much more likely that GPUs are going to the highest bidder/large contracts who are scooping them up to populate/upgrade data centers that are in operation because they are going to get more money per gpu on newer hardware. The "old" hardware might go to a warehouse to be auctioned to the highest bidder or go to a data center coming online, but I highly doubt they are sitting on market wrecking amounts of GPUs just waiting to flood the market. When they go bankrupt and they have to sell a datacenter or two, those datacenters being parted out as part of a bankruptcy deal I could see. Warehouses full of unused GPUs doesnt make any sense to me though.
