Alienware Driver Update!!!

Hi all,

I have an Alienware M17x with a GeForce GTX 460M GPU. I have version 267.xx but I need version 285.xx. Dell does not have this version on their site, and when I go to download the NVIDIA drivers of the NVIDIA site, the setup fails because it doesn't detect my video card and the setup fails.

I hear Dell will be updating all Alienware drivers on October 11, is that true? If not how else will I get my drivers up to date?
