This XEON E5-1660 is more than a 3960X + it is Rev 3.0
4 April 2013
Summary: I bought this product because I wanted to run a genuine PCIe 3.0 build using the X79 Intel Chipset and an Intel rated Rev 3.0 CPU. This paragraph here is my last one but I have dropped it in here so you can get the XEON E5-1660 info before reading the story behind it: I have sold the motherboard and CPU. I cannot take a chance with the Xeon, other than I checked it is in perfect working order and Intel has confirmed it is the newest and best and covered by warranty.
