Newegg.com is usually one of the first online resellers to stock new product lines. However, a quick check shows neither of these boards available yet. In fact, the only E7205 Granite Bay chipset board they list is the AOpen one, which the ETA is Jan. 2003.
I have the Asus board, but I live where they are built. Not sure if they are available in the States yet. The Gigabyte board will only be available here later this month.
If you are getting impatient, maybe look into one of the new AMD CPUs with 333MHz FSB and pair it up with an nForce2 board. They are available and are on par with the Intel platforms (I have one of each).
Price will be very similar as the Granite Bay boards do not come cheap!!
