Hmm, I see at most a 50% increase in motherboard pricing from a dual to a quad socket motherboard and that is with a difference in feature set too with the quad coming with an extra onboard LSI 8 port SAS controller. That is hardly going up non-linearly. (taking an extremely narrow angle ;-p

did you price the quad socket CPUs ? they cost significantly more, too. the newest processor chips are usually the dual socket versions. Also, 4-socket servers may have performance issues caused by 4-way cache coherency chatter, non-uniform memory access, and so forth.
