The ASUS GeForce GTX 680 DirectCU II TOP graphics card delivers a true flagship product for dedicated PC gamers and performance enthusiasts. The TOP-selected 28 nm NVIDIA GeForce GTX 680 GPU has been overclocked by ASUS to 1201 MHz to boost frame rates in games, offering users 143 MHz over reference. Its ASUS-designed DirectCU II thermal design runs 20% cooler than stock, while the twin 100 mm fans keep noise at bay with 14 dB quieter operation.

ASUS has added 10-phase DIGI+ VRM digitally regulated power delivery with 30% noise reduction, working in tandem with durable Super Alloy Power components that last 2.5 longer than reference. Users can tap the greater overclocking and overvolting capabilities of the card through both the hardware-level VGA Hotwire and the software-level GPU Tweak utility. Also released is the ASUS GeForce GTX 680 DirectCU II OC edition, with a 1019 MHz core capable of a 1084 MHz boost clock. This card uses the same DirectCU II cooler and PCB as the TOP version.

ASUS has launched an entire range of DirectCU II-enhanced graphics cards that include the latest technologies from both AMD and NVIDIA GPU rosters. On the AMD side, ASUS offers the HD 6970 and HD 6950 graphics cards with DirectCU II while for NVIDIA, the GTX 580, GTX 570 and new GTX 560 Ti all ship with the advanced cooling technology.

Based on ASUS DirectCU, which uses copper heat pipes in direct contact with the GPU core for up to 20% cooler performance, DirectCU II adds a custom cooler that uses twin 100mm fans for a massive 600% increase in airflow on HD 6970, HD 6950, GTX 580, and GTX 570 DirectCU II cards. ASUS has also launched the GTX 560 Ti DirectCU II TOP graphics card with dual 80mm fans for the best performance in its segment through doubled air power.

Barely 24 hours into the launch of the Radeon HD 4770, ASUS has announced its factory-overclocked, and overclocker-friendly variant of the ATI Radeon HD 4770 (model: EAH4770 TOP/HTDI/512MD5). Giving it the "TOP" branding, the company upped the clock speeds, and backed the product with its Voltage Tweak technology, and its popular SmartDoctor performance control application. The gains end-users have compared to using a reference design accelerator are two fold.

First, ASUS set the clock speeds at 800 MHz (core), and 850 MHz (memory), both 50 MHz bumps over the reference AMD clock speeds of 750/800 MHz (core/memory). Second, using the value-added features, the voltages can be upped from 0.95 V to 1.2 V, increasing the overclocking headroom. ASUS claims the core could be set at freqencies as high as 971 MHz, and 1150 MHz for the memory: a seemingly massive increment over the reference speeds, which ASUS rounds off as a 35% speed improvement. The card retains the reference AMD design, and the most common cooler design partners are currently using. Its pricing and availability are yet to be known.

ASUS, world-leading producer of top quality graphic solutions, has today introduced the ASUS EAH4890 Series-the world's first graphics cards to utilize Voltage Tweak technology. With this innovation, users will be able to boost GPU voltages via the SmartDoctor application and enjoy up to an amazing 15% in performance improvement. For users who are looking for a graphics card offering astounding graphical performances even on default settings, the ASUS EAH4890 TOP will enable an 8% performance boost, delivering exhilarating gaming experiences.
