Multicore CPU's are realistically cheap, Dual and Quad Core CPU's would run you somewhere between $50-$100 in the U.S. Now as for a Multi-Core/Multi-CPU setup, that would cost you considerably more. Especially if you want more then 2 Multi-Core CPU's. pricewatch.com is a great place to judge prices (again, in the U.S.) HTH, C-
