"Unprecented demand" for Athlon 64 X2s causes shortage fear
 

Several European resellers have pointed out problems sourcing these CPUs over the last 10 days. One out of a number of resellers said: "There is a major shortage of all X2 processors from AMD. There seems to be only single core processors in the channel now. Estimated deliveries for dual cores keep slipping further. If AMD makes X2 processors as they used to, where are they going? It must be the big OEMs."

I think it could be the 939 people with singlecore CPUs jumping to a dualcore and thus flooding the second hand market with very cheap singlecore CPUs.
