I've been testing on a quad dual-core box, and there are most definitely "issues" to deal with that I/we have not yet solved. There are some memory issues that I am working on quantifying, probably related to two cores sharing a memory bank and the associated bus contention. First cut on the quad 875 box produced some really ugly SMP results for me, with the NPS "scalability" only reaching 4X generally, where on the quad 850 I last tested on, it scaled perfectly for 1-4 processors... More as I work out the glitches (I hope)..
