Like GTi-6 already stated the board featured in that tweaktown video is the P55 Maximus III Extreme which provides 4 way SLI via NF200, digital PWM, USB 3.0, SATA 6Gb and some other minor details over the regular Maximus III Formula.

The board shown here succeeds the X58 based Rampage II Extreme. No formula as of yet for this platform.
