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.
Pros: Everything you would need for a server. 6 cores VT-D
Cons: Newegg specs states that it supports up to 1866Mhz, but it does not. I should have looked on Intel's spec sheet. I had already spent the money on the 16GB 1866 MHz RAM sticks. http://ark.intel.com/products/75790/Intel-Xeon-Processor-E5-2630-v2-15M-Cache-2_60-GHz
Summary: Using two of these in a multipurpose workstation to do all kinds of very processor intensive tasks. The system is will be doing high-def video editing, audio production, 3d modeling and flow/stress simulations.
Summary: I had been using higher end Core CPUs for home lab VMWare white boxes, but glad I finally took the plunge and went with Xeons this time around.
Pros: I picked up 2 of these to build a VMWare server for my home lab. These are a little on the pricey side but will give me plenty of headroom for running lots of VMs.
Cons: Make sure your motherboard has the latest BIOS to support these new CPUs!! I ordered a Supermicro motherboard and it would not POST. After speaking with Supermicro support, they advised me that I had an older BIOS and would need to either send my board in to be flashed or find a Sandy Bridge Xeon...
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.
