Asus loves its high-end customers. First they dropped out the "RoG (Republic of Gamers)" line as their high-end products, now they have their "The Ultimate Force" (TUF) boards.
The first of this new line of board is being called the Sabertooth 55i. This is going to be a P55 with quite a few unique features and improvements over even their RoG boards. The first is the implementation of what Asus is calling E.S.P. this stands for Efficient Switching Power. This is intended to provide clean power to the CPU and memory as well as the PCI-e Slots and controller (now on the CPU). According to the hard-sell from Asus it raises the efficiency of power conversion from 60% to an impressive 90%.
But the fun does not stop there.
Asus has stuffed in extra goodies like ceramics based heatsinks, direct memory cooling (with an optional cooling fan), "military-certified" MOSFETs, and more.
The new color scheme for the board gives it a decidedly military feel. I am sure this is to allow it to compete (in advertising) against Foxconn's military themed products. No word yet on retail availability or pricing but, given its redesign and high-end components you can bet it will not be cheap.
