This is a lightly used gaming graphics card. This is fully functional, the reason for selling is because i upgrade to a 1080 TI. THERE WILL BE NO VIDEOS SHARED OF IT WORKING. I did not have any videos during the time it was installed and do not want to risk uninstalling my current GPU. I do not want to risk damage to either card. HOWEVER, I WILL ASSIST YOU WITH INSTALL. IF IT DOES NOT FUNCTION AFTER ASSISTED INSTALL I WILL REFUND THE MONEY.
