I've tried nvidia's site since I know they're good about providing drivers for laptops. The latest one for the 555M didn't work. I'm stuck on Nvidia 267.21 drivers. I've tried alienware and they don't have newer drivers either.

I couldn't find the binary GFX key :/ I think they took it out when they created this new machine. I guess it's so new that no one in my LS knows anything about this laptop :/
