In a nutshell, audio processing requires raw speed and power and does not depend so much on the number of cores a processor has. However, more attention to parallel processing is being made by a number of plug-in manufacturers, with some going beyond that to offload what they can to GPUs if you happen to have a hefty video card in your rig. Fast RAM is also important - some huge sample libraries and the use of multiple voices will stop your rig in it’s tracks. From my personal experience, in order of importance: Speed and power of the CPU; quantity and speed of the RAM; fast Storage (as in fast SSDs); cores; GPU. At the end of the day the determining factor will be what you are running and trying to do. Hope this helps.
