Three days ago, AMD apparently issued a letter to several of its partners stating that they are experiencing a shortage of packaging materials for a few of their processors, including the ever-popular Athlon 64 X2 3800+. I haven't seen the letter myself, and it doesn't appear on AMD's site, but it is clearly possible with the high demand during the holidays. With the success of these CPUs, any shortage is likely not to last long, but it may affect purchases in the near future. AMD is apparently now working with more suppliers to alleviate the situation.
