Hello. I read that parts to build Nehalem based PCs should be available on sale around Nov 10 of this year. Yet, some of us predict that the new mac pro should be out in Jan 2009. How come there is a 2-month gap? Anybody knows how many cores and memory slots will the up-coming Mac Pro have? It seems that on the PC side, motherboards for the Nehalem have one CPU socket and four memory slots to support triple-channel performance.
