Pulled from used Alienware laptops. All in excellent working condition. These cards support SLI unlike MSI GTX680M 4GB gpus.
These cards will work for Clevo P150HM P150EM P170HM P170EM laptops and with some Alienware and MSI laptops.
I can flash vbios accordingly before shipping if you let me know brand and model of the laptop that you intend to use these cards.
