Intel Xeon E3-1245 

Released April, 2011
  • 3.3 GHz
  • Quad core
7.6 Out of 10

Interestingly enough, vague rumours of a 15 core chip have not evolved into anything concrete as of yet, at least not to be released at the same time as the others.

These prices are currently listed as consumer based pre-order prices, and equate to ~12-30% more than the current Sandy Bridge-E offerings.
