The Asus Rampage III Gene and the Sabertooth are both X58 boards, but have implemented that chipset in very different ways.  The Rampage III Gene is an mATX board, just like its predecessors and the Sabertooth is a member of the TUF series.  The TUF series are designed to a variety of military specs, the capacitors, chokes, and MOSFETs have much higher resistance to moisture and temperature and that shows in the 5 year warranty offered, as opposed to the 3 years for the Rampage.  See them both at The Tech Report.
