TTYL Not true at all. If you consider that a system running any modern OS like Windows (NT, 2000, or XP Pro for SMP support), Unix, etc actually consists of many process and threads all running, then 2 CPU's can have a noticeable advantage. Take for example, the ability to run a CD burner or other processing program in the background, while you continue to use an application interactively, like photoshop or similar. The OS will utilize both CPU's to allow both processes to run with less slowdown. Visit www.2cpu.com, this site is dedicated to spreading the word about the advantages of multi-processing.
