I just loaded Windows 7, reading about Windows 7 the drivers in Vista 64 should work with Windows 7 64, I knew there was not a certified Video Driver for this machine. BTW I have the Quadro 2700 Video Card. When I did a Windows update it installed a driver for my card, have no idea where it came from. I was wondering what everybody was using and how good of luck they were having with that particular video driver. I am off to see how mine is going to work.
