The FXAs all have mobile processors. People who bought the predecessor to these, the FX210, found out that they had the AMD 800 Duron desktop chip (Spitfire?) instead of a mobile processor. Without Powernow features their stock battery went dead in about 45 minutes. The FX210 can be upgraded with the 900mhz Duron for $125, 1ghz Athlon4 for $200ish, and the 1.1ghz Athlon4 for $275ish. I am curious to find out if the FXA32 can be upgraded to an Athlon4 as well. I just don't want to crack the case open yet.
