Asus unveiled a new motherboard in its newly-developed "TUF" (The Ultimate Force) Series, the SABERTOOTH 55i.

The TUF Series is specially developed to meet the heavy computing demands of power users and perform well even under extreme conditions. Such computer enthusiasts often demand high-quality motherboard components and the most stable computing platforms. To achieve uncompromising stability, TUF Series motherboards have undergone a more stringent testing program than what most motherboard producers currently undertake. Solidly constructed and equipped with resilient components that have passed demanding military-style testing, the TUF Series triumphs over the harshest operating conditions to deliver robust performance.

The debut SABERTOOTH 55i model, designed around a "Marine Cool" concept, incorporates the Intel P55 chipset and "tough" features to give users a supremely solid and stable computing platform.
The ASUS SABERTOOTH 55i motherboard, equipped with the new CeraM!X heatsink, delivers exceptional cooling to active components and uncompromising system stability even under intense operating conditions. With its advanced ceramics-based composition—commonly used in the aerospace industry for heat insulation—the heatsink dissipates heat rapidly to achieve ultimate cooling. Ceramics replace traditional anti-oxidant compounds to create a microfin surface texture for enhanced cooling. This rough surface offers an expanded area for heat induction into the surrounding air. As a result, more heat is rapidly conducted away from the active system—allowing users to enjoy previously unattainable levels of stability.

The Asus Sabertooth 55i has a LGA1156 socket for Intel Core i7 and Core i5 Processors. There is no word yet on pricing and release date from Asus.
