My 2c (OK, I'll take 1c): The main advantage of multiprocessors is in multitasking. For almost all applications, only one processor is doing the work, so you won't see a speed advantage. And even with two apps running, if one is processor intensive, you will have trouble running another app. A nice thing about 2 cpu's is if you are doing something like copying files from one location to another, you can still do other non-intensive tasks like browse the internet whereas with one cpu you just have to wait. This is strictly my perspective from using an old BP6 with 2 Celeron 533's and doesn't reflect any general knowledge of multiprocessing. Probably some types of server software, for example, are designed for multiprocessing and the benefits are much greater. wily

Would you want a dual cpu at 1G hz or a single cpu 2G hz, both running windows xp pro? I would go for a newer hyper-threading Intel processor. You don't double the performance by going to a dual CPU motherboard. The numbers I have heard in the past is you only get about a 30 to 50% increase in performance. The newer Intel hyper-threading CPU's have the capability to run multiple processes at one time just like dual CPUs but they do it one CPU. Intel claims hyper-threading produces up to a 25% improvement in performance
