That's right - at this very moment, you could own an Xbox 360 sporting the much fabled 65nm CPU and GPU. It appears - according to a thread on the official Xbox forums - that Microsoft has, under the guise of the recently released Halo 3 360, soft-launched the 65nm edition of its console.
What does this mean in layman's terms if you happen to own one? Firstly, it means you're much more awesome than all of your friends. Even the hot ones. Secondly, the 65nm chips run cooler and consume less power than their tardy 90nm counterparts... which can be found in every other Xbox 360 in the world. Except your one, of course.
We were under the impression for a long time that such hardware would debut in the Elite. But, it didn't. I don't entirely understand why Microsoft hasn't made a bigger deal out of the 65nm Halo 3 consoles... maybe they were concerned they'd anger everyone who's already forked over the dosh for the Elite.
Finding out whether you're 65nm-enabled - as it were - is not exactly simple: you need to take your console apart. Let's just assume if your Halo 3 box is a lot cooler to the touch and quieter than a standard unit, you're probably one of the chosen.
