Thank you for your answer. I've already ordered a brand new one from china for 76$, so hopefully it was the right choice. For the interface, i will share my experience in case of anyone is wondering. I tried 3 different cards with the exact same interface and size. The first two were Dell 6970m and Ati Firepro M8900, which i couldn't get video output from the laptop screen and i haven't had the chance to check the hdmi or vga outputs. Then i tried GTX 660m (2GB version) and for this card laptop screen and hdmi wasn't working but vga output was. But it didn't let me install any windows drivers, since i believe the card wasn't fully recognized by the laptop and windows. So all of them were incompatible to some degree, despite the same interface. In various forums some people reported that they have successfully installed HD 7970m v1.2 with a special vBios(non Enduro Clevo vBios) but i couldn't find this card locally either. So hopefully this helps someone.
