Although Intel's Westermere-EX was last updated in late 2011, the specs are still pretty good. Those CPUs have up to 10 physical cores (20 virtual thanks to hyperthreading) and 30MB of L3 cache. The clock speed isn't amazing, but that's to be expected when you have to deal with the heat from 2.5 billion transistors.
The Ivy Bridge version is supposed to ship in Q4. It should have even better performance.
