So many things to play with on this board. Problem is work is getting in the way of tweaking with it.

Really like this board & the way the EKWB mounts on the X99.

There were some negative comments about the BIOS of this board and a few DOAs - but perhaps those have all been solved, because this motherboard as of mid-2017 worked like a dream out of the box. I was in two minds about this board and a cheaper X99, but in the end all the bells and whistles in this beautiful piece of kit sold me. There are USB 2, 3 and 3.1 ports - there's wifi, dual linked Intel network, there's a thunderbolt 3, as well as a PXE chip to help chips like the 6800k overcome their 28 PCI lane limitations. The board is rugged and while I initially wasn't a fan of lights - I have now been suckered in, and purchased additional LED strips, a glass side to the case - and my entire PC now pulses coloured lights as music plays. Knocking one star off for still being an expensive board.

Wanted x16/x16/x16 and got it! Small sacrifices were necessary, but no biggie.

The board is quite amazing, I'm really happy I didn't go with any other brand/model. There are lots of handy features like built-in Wifi and there are 8 SATA ports which is perfect for me. Plus, 128 GB Maximum RAM Support? I mean are you kidding me? It's amazing! Don't forget the x16/x16/x16 feature.
