Well good news for me. I got the 2 780m that I bought working in my m18x r1. By working I mean displaying video. I was on A05 locked and was unable to get it to post. All I got was a black screen with one beep. I installed the 580m back in. Updated to the A05 unlocked bios. Switched it to IGFX. Reinstalled both 780m and changed it back to PEG. I got video now so that's a big step in the right direction. Now if I can just get my modified INFs to work with this friggin beta driver Nvidia just released ill be in good shape.
