I'm new and building my own PC.
I'm planning to include two cpu's, both Intel i7-3960X. I'm also planning to have as much RAM as possible. Using Windows 7 Ultimate (64-bit, x64) as my OS with the RAM limitations being 192 GB
It would really be helpful to know what you want to do with your pc. In order to run dual cpus, you do need Xeon E5 series processors. They will both have quad channels so you can run 8-16 sticks of memory. That processor is probably overkill for your build unless its for a sever. Its also over 4 grand. Not necessary unless you have really deep pockets. 128gb of memory will cost around 1700 bucks. Both the processor and that much memory is necessary for most desktop uses. One of our high end workstations would probably suit you unless you want to build your own. http://jallenlabs.com/buy/
