The Asus P8B-WS is designed to work with the Intel® Xeon® E3-12x5 processors (the 5 on the end means that it on the IGP or intergraded graphics on processor). The Z68 can do everything the P67 can do and has 3 additional features that the P67 does have. Those features are:
-Intel SRT (Smart Response Technology) use a small SSD (<64GB) to cache data for commonly used applications
-Support for the IGP- good for back up graphics and most of the time these boards come with the Lucidlogix Virtu software to switch between dedicated video and the Intel Quick Sync.
-Intel SATA III controller- said to be better performing then the Marvell controller on the P67 boards.
