Wonder about the X2 4400, 4800 and the Opterons ?
if you're planning on building your own or upgrading your system, AMD has confirmed HUGE price cuts for july 24. you'll be able to take advantage of these prices the same day since athlon64s (and amd2 mobos) are already in the channel. intel core 2 duos (conroes) will be similarly priced but probably won't be readily available until the first or second week of august.
athlon64 x2-5000+ $282 (now $649)
athlon64 x2-4600+ $224 (now $522)
athlon64 x2-4200+ $175 (now $339)
athlon64 x2-3800+ $149 (now $277)
athlon64 3800+ $102 (now $246)
athlon64 3500+ $79 (now $130)
