I am a new arrival here. I found the information on this site helpful, and today I became a paid member so I can download. I have a M17xR3, Win7, and am attempting to install a GTX880m card (from a GTX460m). My take from the previous posts is the 337.88 driver is still the desireable one. No? Today I have successfully downloaded and unzipped the 337.88 driver from a link provided in an earlier post in this thread. I have been unsuccessful downloading and unzipping the associated modified nvdmi.inf file in the same earlier post. The file downloads, but when I attempt to unzip, it fails saying fiolder is empty. Can someone provide me with a working link please? Or... Is it possible for me to make the required changes in the nvdmi.inf file myself? What changes do I need to make?
