Got the Big Bang setup up. This has been a great motherboard to work with and the build quality is fantastic. This is the first motherboard this year out of 4 or 5 that I have setup that has detected both keyboards and a working mouse in the BIOS on the first try. Using BIOS 1.4B2 at the moment and haven't had a single hitch.
The Gatling gun VRM heat-sink is pretty subdued and looks decent. The ammo heat-sink does look pretty cheesy in pictures but in real life it looks a tad better. The tips actually look like real brass, but in pictures the whole thing looks like plastic. Although if I stick with the board I will most likely get water blocks so that will all be moot.
Even the X79 RAID was easy to get into and setup if you have the proper drivers. Something I learned the hard way with the RIVE!
UEFI is a pleasure to work with and nicely laid out. Both MSI and Gigabyte have great BIOS's now, easily up to par with Asus.
As for the 5x1 Display setup, having issues with all of the monitors being detected/displayed. Even in regular desktop mode, haven't even gotten to Eyefinity yet. I have 24 gauge super high quality Display Port cables arriving tomorrow so hopefully this will get resolved.
