Found this, it came out yesterday : http://xtreview.com/review194.htm it's benchmarks for a SR windows machine. Looks good, but seems to be a big difference between 2.2 and 2.4 GHz. Power savings looks to be much better than napa. One thing I found really interesting in (at least in their tested system) the machine booted 2 seconds faster with Turbo Memory (flash ram) disabled! But it is a window machine, let's hope apple tailors osx/bios to take advantage of the flash ram.
