Summary: I love this board. It is my second purchase of this CPU board and I was not disappointed either time. I did have the occasion to talk to ASUS technical support to clarify a driver question and their support was wonderful. Great value, product, and support - the technical trifecta - in my humble opinion.
Summary: I bought this MB for a workstation using 2 Xeon E5 2620 hex core cpus. It works flawlessly with a non standard GTX 560 ti and 8 gigs of ram. I use iray, a host of adobe rendering software, cad, and bunkspeed.
Summary: Don't bother looking for an SSI EEB chassis. Almost all are built for Intel boards where the system will spend its life basking in a dreary, poorly lit computer room while being pummeled by gale force winds from whiny rack style fans. Instead look for water cooled solution from Corsair (the common review), or even better use the Coolermaster 812 with vapor chamber tech to keep your lga2011 xeon 8 core processor cool.
Summary: Like Henry, I've been building high performance workstations built on this ASUS motherboard with E5-2603, 2620 and 2630 XEON's and the board also supports the newer E5 v2 CPU's which boast up to 12 core versions, and I have found it very good in all aspects and very reliable for my clients. Either with 64GB quad channel non-ECC DDR3 or with the full 256GB ECC registered RAM.
Asus Z9PE-D8 WS Workstation Board Dual Socket 2011

Summary: I got this as I was wanting to upgrade, but did not want to need to again for a long while. This is a well designed board and is forward compatable with the new emerging speeds and connections. Only drawback I have found is that I needed to upgrade my OS as well to take into account the extra RAM and starage requirments. As such, 64Bit OS is needed to run in high speck setup's. When getting this Board, you need to think about the case as well.
