I have a G75VW and I have a GTX 670MX ready to be installed. I know how to physically swap the video cards but I'm kind of confused about the vBIOS. From my understanding I need a modified BIOS in order to run the computer after the 670MX is installed. How can I get a modified vBIOS and when do I flash it before or after the I install the video card? I will appreciate any help!
