For what it's worth, I've been running a Dual 550 system close to a year
now, first with NT 4 WKS, now with W2K. I was running NT 4 WKS on a single
chip system before so that part of the change didn't matter. Of course it
doesn't feel like 1,100MHz, but it doesn't feel like 550MHz either. The apps
may or may not take advantage of the second chip, it doesn't matter to me. I
can have more apps running simultaneously and don't have a speed/resource
degradation because of it. Things just happen, the system is definitely
quicker to respond, no matter what is running at the time. I can say that
now I am actually multitasking, or closer to it, instead of fast swapping
like before with a single chip and W9X. After working with a dual system I
won't go back to a single chip system.

HTH,

Jose
