The new Alienware M11x uses the NVIDIA GT335M. That would explain/confirm what NVIDIA said about the 300 series being used in notebooks, etc., and skipping to the 400 series.
Man, serisouly, WTF. They just came out with the ION chipset, and now this crap? My brother just spent 500+ bones on an ION and now it feels like it's already outdated. I would have shelled out another 200 bucks to get a M11x.
