The only processor-intensive tasks that you will have are decoding the mpeg2 streams, and the commercial flagging threads.  Keep in mind that if you are going to be doing any compiliing of source, faster procs will speed this up.  I have a celeron 2.0ghz in a frontend/backend combo, and it is overpowered.  So, you should be able to get away with the cheepest CPU.
