The benefits are minimal in nearly every circumstance when using hyperthreading... I imagine there are times when it may hurt you even... but I can't imagine that is the case for you. Considering that most future computers will be smp (dual core) then I would say go with the smp kernel as it may make transitioning to future hardware and kernels easier?... And who knows, now that smp is getting more common, perhaps the dev's will start to actually write most of their apps with smp in mind?
