    Steven,
    If you are wanting better performance, actually doing two things at
    once, then go for a dual cpu motherboard. If you are just wanting
    speedups, then go for the Opteron/Athlon64 cpu. Hyperthreading was
    just another gimmick Intel tried to use for an already bad cpu, the
    Pentium IV.
