A new ranking of U.S. metropolitan areas' tech prowess has been released, and annoints Silicon Valley as No. 1 due to 226 acquisitions of privately held technology companies in 2012. The list comes from PrivCo, a research company offering insights on private companies.

While the premier ranking of this Northern California innovation hub isn't surprising, the area was outdone by both New York City and Boston when evaluated based on the price tag of the largest deal made in 2012.

Infrastructure provider Zayo's acquistion of AboveNet for $2.2 billion outdid Oracle's $1.9 billion purchase of talent management company Taleo. In No. 3 ranked Boston's top deal, finalized in Dec. 2012, Berkshire Partners bought Lightower Fiber Networks for $2 billion.

Here's the complete top ten list:
