If I was buying today (and I am not as I am leaving for a 10 week vacation in Hawaii in just over a week), I would definitely consider the Northwood IF performance (including overclockability) was my sole criteria.
I would say, Googlegear got these Intel CPUs probably from the overseas shipment as they are also selling in Japan. Obviously, you are going to pay a premium for a PRErelease. it should be a little bit cheaper when there is some competition selling them. And in a month or two, when the novelty wears off, they will drop further and a BIG drop when the 2.4 or 2.5Ghz CPU is released.
