I got the i7-3770 to upgrade a old Dell Optiplex 3010. The CPU works fantastically. Also, Karrie's Odds and Ends had this CPU for sale for 50% of the cost of other sellers, packaged good enough, and it had fast free shipping. The CPU only took 4 days from purchase to arrival which is like Amazon speeds. So, overall very impressed with Kerrie's Odds and Ends and I will most likely buy from them in the future.
