Kinda Faulty RHD 6870 Value

So I have a partially faulty 6870 and I am wondering what to current worth of the card is

 

The card originally had 1gb of VRam, but something happened to it and now it only has 775mb or somewhere around that range left that are usable and it seems to brick itself to where it requires a system restart to get it to go back to it's normal state when loading flash videos (aka youtube). I all ready have a GTX 770 that I bought months ago to replace it. It cannot do any mining of any sorts.

 

It's thermals are still beautiful so it's not an overheating problem

 

I just want to see if reselling it is honestly worth it or if I should just use it as a coaster

I would advise you to not sell any components that you are having any type of problem with. It could come back to bite you. It wouldn't be worth the headache for the $40 you might get for the card. plus it could suck for the buyer too.
