The cheapest Nehalem-EP based Xeon will start selling in the last days of March for $285. We are talking about Xeon W3520, which will run at 2.66GHz. Just as any Nehalem CPU, it comes with 8MB of L3 cache and uses Intel's LGA 1366 socket.
Currently we don't see any plans for lower speed Nehalems, and we believe that this CPU will do very well in the server world."
