I went to MicroCenter to price components today for a new system and ended up buying most of what I need there.
The best item of note was the Q6600 for 199.99. Their site lists it as 275.99 but in store they said they had dropped the price on it yesterday. I don't know if it was a local thing or not (Store in Overland Park, KS) or chain-wide.
In any case, fantastic deal. The price on the box says 339.99 but the receipt says 199.99
