Mate dont get me wrong but SMP rocks My 5 year old dual Pentium 3 servers are like only a third off the pace with todays core 2 duo.
As I keep saying, getting the masses to go from 1 core to 2 core will yield them great results and benefits (partly due to windows INEFFICIENCY / deficiency or just plain old user incompetence
And so selling the sheep quad core should be easy but unfortunately will not yield as good a performance leap as going from 1 to 2 cores. Unless of course there will be new hardware and software made available to make full use of quad core.
