One of the neat things about Haswell-E is that it brings down prices on higher-core-count CPUs considerably. The cheapest reasonably-clocked 8-core Intel CPU (the one in the 8-core nMP) had a TRAY price of $1700. Haswell-E brings that down to $1000. 6-core drops by a similar percentage ($580 to $390). So what I'm wondering is whether these changes in pricing mean the next generation nMP will offer significantly better bang-for-the-buck? Today Apple charges $2k to upgrade from 4 to 8 cores, but it seems like that'll be a lot harder to justify going forward.
