Than how will dual core socket 939 Athlon 64 CPUs work? When are dual core Athlon 64 CPUs coming out? Is it worth the wait, or should I just go with a single core Athlon 64, and forget about SMP? How important is SMP for gaming if you have a file downloading, and AV running in the background while playing a game? I know SMP won't help games by themselves, but it will help multitasking, and downloading a file while playing a game is multitasking?
