My friend went last night to the Paterson, NJ, Micro Centre, where they had over 100 Q6600s. Again, no E8400s. He decided to pick up the Q6600, but then things went pear-shaped: both on the telephone and in person, the staff insisted that you have to buy a bundle to get the Q6600 at the $200 price. Now, this Q6600 price is blazoned over Micro Centre's home page, and there's nothing about any mandatory bundle! Has anyone heard this sort of condition at any other location?
After a bit of back-and-forth, a shop assistant eventually convinced my friend to buy 4 GB of Corsair TWIN2X4096-6400C5DHX for about the same price as it's offered online after rebate. So he wound up spending slightly less than $300 all told for a Q6600 and 4 gigs memory, which isn't too shabby considering a few weeks ago he would have paid nearly that much just for the Q6600.
I've decided to wait for E8400s, though I did pull the trigger on 2 GB of Corsair TWIN2X2048-6400C4. Newegg had a code dropping it to $69 - $40 rebate, and the rebate period concluded with Leap Day. I intend to buy the Abit IP35-E next week, and then it's just a matter of waiting for the E8400. I'm inclined towards the Penryns owing to their greater efficiency, and I'm a bit frightened of what I've seen of quadcore power usage.
