don't forget it is logical virtual processor..
means when your program is having overhead, you will get downtime..
as the processor timing is totally different with their previous families, programmer haven't yet to adopt these features into their calculation method..
you should remember back that the HyperThreading Technology which they introduce as "fake" dual core, also their Pentium D 800 series, which features 2 physical processor cramped into 1 physical socket..
of course, this time their memory management "should be" better already, but the memory pair is 3 pairs.. or should I say, 6GB/12GB max memory?
