Thanks guys, I didn't know about the sysopt site. It's now on my bookmarks. DaveW: I am not aware of any processor-imposed limitations on SMP. It is true that certain CPUs actually implement SMP functions, but such integration is not crucial. For example, here's an excerpt from the sysopt page: This sounds a great deal like SMP is motherboard-dependent, not CPU-dependent. Naturally, whatever SMP functions are not implemented by a CPU in question, would have to be provided through the chipset. Also, I don't consider dual configurations all that exciting. If you are going to lay out additional circuits, you might as well go all the way. The more processors, the greater is the economy of scale. I agree that Intel is probably making a strategic blunder in ignoring non-corporate SMP; if some company makes a serious foray into this, they will probably launch the next revolution in performance and grow at fantastic rates. Plus, bundling multiple cheap CPUs into one box might be a very handy way to handle the extremely low profit margins. Plus, just imagine the ad campaigns!
