The above one supports upto 4 CPU, but supports less RAM.

I'm not sure exactly what I'm looking for to be honest. Audio processing seems to be difficult to get glitch free results with anything short of a supercomputer. I just figured dual quad core CPUs that were capable of hyperthreading would have to be more than adequate given the appropriate drives, memory, etc. Thanks much for your reply. 4 CPUs may be a bit of an overkill especially for my wallet!
