Hi guys! Trying to get the hang of using this beast. Amongst being my first laptop and Mac, it's also the first computer I've had that has used more than one video card so I am little confused when it comes to updating drivers. On a MBP do I need to visit the nVidia and Intel websites to keep up-to-date with drivers or will Mac auto-update them for me? Also, do I need to do anything in particular when updating two separate drivers on one computer? Eg. Turn on/off auto-switching in Energy Saver?
