Neither the number of cores, the amount of RAM or the type of hard drive
you have is going to have much effect on jack performance, unless we're
talking really poor hardware.

Some audio devices work better than others.
And, there is always the chance of IRQ conflict, causing one piece of
hardware to disturbe the performance of another.
