Summary: After comparing the E5 series, this processor seemed to be the best price performer. With the ability to boost to 3.1GHz it's faster then you would think. I love the hyperthreading and the virtualization.
Summary: THIS XEON PROCESSOR IS KICK ASS. I HAVE ONLY INSTALLED ON MY DUAL SOCKET ASUS WS BOARD AND IT SLICES AND DICES THROUGH ALL OF MY JOBS. I AM COOLING IT WITH A CORSAIR 100HI COOLER SO THE TEMPS STAY DOWN BUT IT POWERS THROUGH THINGS WITH EASE. IF YOU ARE BUILDING A NEW SERVER, LOOK AT THIS XEON.
Pros: Fast CPU with six-cores. Have two of them installed in a Asus Z9PE-D8 and I love it. Great for 3D modeling. It does help cut render time by a little over 50%. I also use it for gaming and it works great.
Cons: Wish it had a higher clock speed for this price but not a big issue to take of an egg or two.
