I sell my old graphics cards on ebay.
Find your parts in used condition on ebay.
Then filter on completed auctions,
In green you will see what the part actually sold for.
Do be careful who you sell to.
I recently had a buyer return a different(and probably defective) card than the one I sold him, claiming it was defective.
Fortunately my listing showed the serial number and some hidden identifying marks which were not present on the card he returned.
The incident has been reported to ebay and the investigation is ongoing.
That is insane! I would have never thought to include the serial number in the pictures... I'm going to start doing that.
Also - yes what he said. I sell my stuff on ebay a lot. Just make sure to do what he said with the pictures, and make sure to say sold as is, no returns. and include something along the lines of "it works for me, but I cannot gurantee it will work in your system". stuff like seller protections
