ZERO - WHAT FREAAAKIN CPU TYPE DO YOU PLAN ON BUYING?
Two individual cpus? (two peices of "matter" = blah for all but servers)
One cpu with a dual core (multitasking)
Just buy the Intel Core 2 Duo. (Doesnt matter which one because they all desimate AMD when overclocked. ) They have dual cores and can handle, optimally, two processes at the processor speed. Or if the process is multithreaded, then up to 1.5 times the processor speed.
