I just sold my used Nvidia GTX 1080 Ti FE for more than I paid for it brand new.
This was a card that released four years ago and I bought three years ago for around $699 direct from NVidia.
Even after shipping and fees on eBay I got over $700 on an auction that I started at $360.
Even three years ago it took me months to find one.
I'd like to get one of the Ryzen 9 5900x CPUs but that's not happening right now.
This is nuts!!
