Features -
In the current market motherboard (and indeed almost all component) performance is very close. The days of a large performance advantage between boards using the same chipset are long gone. That is unless someone makes a HUGE mistake (like runs traces completely wrong). Now, the thing that differentiates different products is the features. These are things like power management, extra slots, better audio CODECs etc. It is these items that R&D teams work so hard to drop into what are really identical pieces of hardware at their most basic level.

Excellent -
3D Power
Quad Channel RAM
Dual 3D BIOS
Wireless N and Bluetooh 4.0
Three-Way SLI and Crossfire X

Our list here is not as extensive as we would have liked to see. Many of the items that we are talking about due to the newness of the X79 platform will be stock features very soon. The advent of Three-Way SLI and Crossfire on all X79 boards is something that will soon drop into our Floor Mats listing.
However other items like the 3D Power and the Dual BIOS are nice touches that we hope to expand upon in the second half of our review.

In the middle (sort of good) -
110db Audio

I am something of an Audiophile and this, If it is real) is a great feature and can improve the overall quality of the board experience (especially gaming). We are looking forward to seeing just how good this sounds once we get it on the test bench.

Floor Mats -
On/Off Charge
On-board power and reset controls

These are items that we are finding on just about every board in this class now. They are nice, but as you see them more and more they will not be the reason you buy one board over another.
