no they are 939 pins, but now athlon 64 is taking place of FX's, except FX-55, if i've to write down the AMD's with reference to their design and power, then this should be like that:
1: Athlon FX-55
2: Athlon 64 4000+ and FX-53 = exactlly SAME, just box color is different.
3: Athlon 64 3800+
and sorry, i made a little mistake, its FX-51 that has vanished from list, not the FX-53 (but it will as well SOON)
