Hello all , I have an alienware 17 R5 with an Nvidia GTX 780M . I have decide to change the vga card with an 980M from eurocom and a friend of mine install the card to my laptop. I have also a 330w power supply. I have a feeling that the card is not so much powerful than my 780M . I search google and it takes me here in this forum and i read something about throttiling of the vga. I try to install latest drivers from nvidia but i take an error in the installation proccess. I have read about 60% of the topic and i didn't understand much. I must have an edited driver for this card ? I must my card bios to stop throttling ? Thanks a lot
