Microsoft has started shipping Xbox 360 consoles with the new 65nm CPU technology that uses less power and runs cooler.

A user on the Xbox forum purchased a Halo3 Xbox 360 that came with the highly anticipated improved technology.
Whether or not these new Xbox 360s will run more stable and have less failures is not clear yet. The Xbox 360 consoles with the 65nm CPU technology are apparently not marked as new on the outside, which I think is really an issue for consumers.
The chances are good that these new Xbox 360 consoles will run more stable and they apparently save 30% of energy. Like with the HDMI feature Microsoft should openly mark the new generation of Xbox 360 boxes to be clearly identifiable by customers.
