    I was hoping to find out everything I need to know about the 2010 Mac Pro westmere processors.

    What advantage do they provide? How might I benefit?

    It's basically just a die shrink of Nehalem (32nm vs 45nm), that allows 6 cores to be used without extra power consumption. There is new set of AES instructions which will improve encrypt and decrypt rates and improved virtualization technology.

    I dont know what any of that means except for "less power consumption"

    Encrypt and decrypt is locking the file so it needs a password if you want to open it. More common under Windows because OS X seems to lack good apps for it but it's pretty CPU intensive and the new AES speeds it up a lot.

    Virtualization means running two or more operating systems at the same time. The improved technology should improve the latency.

    It looks like you won't benefit from these small extras, they are pretty minor
