AMD ANNOUNCED a surprise round of price cuts today, and they are good through the end of the year. They are only on S939 Opterons, AKA 1xx series, but are good on PIB and Tray parts.
This tells me that OEMs shifted to Socket AM2 a lot quicker than AMD had hoped, and there is a pile of parts sitting in a warehouse waiting for a loving owner.
Upgraders, Christmas arrived early, those tray 170s and 175s look pretty good
