This is the PCPartPicker chart that I monitor: https://pcpartpicker.com/trends/price/memory/#ram.ddr5.5600.... - $900 for 2x32GB, used to be $200 a year ago.
The memory in the PC I put together early last year is now worth about three times the total cost of all the parts I used to build the thing. It is absolutely crazy.
I was thinking of upgrading the video card to something better, but looking at the cost of replacing that Quadro? I might just stay put for now. Costs on those have also pretty much doubled.
