Thanks.
No performance gains, just runs a little cooler if the new console you
purchase ends up having the new falcon mobo and the 65nm cpu on it.
Still, the overheating problem associated with the 360 is due to the
gpu in the console, not the cpu. And the gpu is still the older 90nm
fab and the new 65nm gpus won't be going into the 360's until about
this time next year.
Make sure your Lot# is 0734 or greater and has a later manufacturing
date of 08/24/07, as reported here,

I honestly doubt that the new heatsink, along with the new mobo and
the smaller fab 65nm cpu will significantly reduce the 360's RROD and
overheating related problems though. It's just woefully
underventilated in the first place. And they haven't dealt with the
biggest culprit of the RROD issue, the gpu.
But it still doesn't hurt to get your hands on the newer lots.
If you're in the market to buy one, try to get one with a lot number
of 0734 or higher (or manufactured date 8/24/07 or newer). They should
have the cooler chip-set in them. The lot number printed on a white
sticker found on the left side of the boxes.
The Arcade's won't have the new chip, at least not for a while. Only
Elites and Premiums made by Team: FDOU. Lot #734 or higher for a
chance at one, Lot #738 or higher to pretty much guarantee yourself
one.
I doubt there's any performance gains, but the one I bought last week
seems to run quieter, and it came with the newer BenQ DVD-Drive as
well. (Which is something I was pretty concerned about since the DVD-
Drive on my first 360 died a few weeks after the Warranty expired for
it. The BenQ Drives are supposed to be more reliable, so I'll see how
long this one lasts.)
