High-performance graphics workstations are using 2 cpus. Todays high-performance graphics box is next-year's standard PC, if you look back over time. SMP boxes do _not_ mean every program has to be SMP-aware. There are lots of things running on a single machine... explorer... a web server... email... games... all of that can take advantage of 2 cpus without any modifications of any kind... and for those programs that are modified, they can run even faster... But as I said, there isn't much point in arguing whether it will or will not happen. We only have to wait. It won't take very long to see...
