I said it before and I'll say it again - the vendors are the criminals here. There are vital industries that need GPUs for their viability - video games, medical research, engineering etc. and they should filter out the robo buyers to allow these people to purchase the graphic cards at reasonable rates. Right not RX570s are going for $200 on ebay right now... A 4 year old mid-tier graphics card....

Just allocating some GPUs to a wait list would be enough.

For people like me who cannot wait for GPU to become available you can get a very cheap usb-hdmi dongle off of amazon for dual monitor support. It works well enough for what I need it to do.
