Summary: This is an update from I7 920 definitely huge upgrade in performance and even in temperature. I7 990x runs cooler than 920. Setback is the overprice. It transfers your system's computing power from 2010 to 2014.
Summary: Thanks to this seller, my long disheartening search is over. I searched for months for a specific replacement for my now obsolete mother board and was nearly out of options until I found Mustang 717! Yahoooooo! Thanks! It was and is working perfectly!
