AnandTech has a comprehensive review of the Asus P5N32-SLI: Dual x16.  It has many innovations on it, and one of the main focuses on this board seems to be improving the quality of power that the system recieves.  You night wonder what that means to you?  It means better overclocking potential … that’s what!
“The Asus P5N32-SLI Deluxe is outstanding and deserves serious consideration if you are an Intel enthusiast. It is hard to quantify this statement, but after spending considerable time with this board, it is truly a cut above most other boards in both quality and performance. The board is obviously targeted at the Intel gaming enthusiast, but it should not be dismissed as an everyday solution for people who are able to afford its $210 price tag. The exclusive 8-phase voltage regulator power design is a must-have feature and is one of the main reasons why this board performs so well at overclocked settings. While I had initial doubts about the fanless heat pipe design based upon previous experiences, the design that Asus installed on this board has guaranteed that I will be looking for this type of cooling system in future boards. Asus also implemented their unique Stack Cool 2 that involves a special design on the printed circuit board that dissipates heat from the board components.”
