GV-N660OC-2GD represents "Kepler sweet spot" which brings gaming experience with ultimate combination of performance, power efficiency, and affordability. Supported by NVIDIA® 3D Vision Surround, 3D Vision™, PhysX® and 2-way SLI®, GV-N660OC-2GD guarantees an extreme experience. Equipped with the innovative Kepler GPU Dynamic Clocking technology, GV-N660OC-2GD dynamically adjusts clock speeds to bring out the best performance for every gamer.

WINDFORCE™ cooling technology – Designed for Gamers
GIGABYTE introduces WINDFORCE™, the latest cooling technology that differentiates the brand's graphics cards from the rest. GIGABYTE understands that a fan is crucial to the graphics card, and knows that this is what gamers really care about. Therefore, only the fan with the most efficiency is selected for GIGABYTE WINDFORCE™. To qualify for WINDFORCE™, the cooling solution must be equipped with anti-turbulence inclined-fans and pure copper heat pipes. Inclined-fans redirect airflow and help to reduce excessive heat and turbulence. Depending on its orientation, there are 4 types of inclined-fan designs: outward-inclined, 3D-inclined, parallel-inclined, and mirroring-inclined. Each type contributes to generating excellent exterior airflow for efficient heat dissipation from the interior GPU core.

WINDFORCE™ 2X 100mm Fansink with "Triangle Cool" Technology
GIGABYTE always dedicates to providing the best thermal solution for serious gamers. GV-N660OC-2GD features WINDFORCE™ 2X Cooling Technology, GIGABYTE's innovative new generation fan solution with two 100mm patented anti-turbulence inclined fans with "Triangle Cool" technology and two 8mm pure copper heat pipes. The combination of anti-turbulence inclined fans and pure copper heat pipes helps to reduce excessive heat and minimizes the flow of turbulence between fans. "Triangle Cool" Technology combines fin with clip module in a special triangle shape. Based on the original anti-turbulence structure, the new triangle cooling design enhances the efficiency of heat dissipation dramatically by minimizing the flow of turbulence between fans. By enlarging air channel on the graphics card vents and creating a more effective airflow system in chassis, GV-N660OC-2GD with WINDFORCE 2X definitely brings out a better cooling performance.

Equipped with GPU Boost technology, GV-N660OC-2GD guarantees gamers with faster and more power-efficient performance. This technology dynamically maximizes clock speeds to bring out the best performance in every game. GV-N660OC-2GD also provides ultra-smooth gaming solution with NVIDIA® gaming innovations like FXAA/DXAA and Adaptive Vertical Sync; it adjusts vertical sync based on the current frame rates for maximum playability dynamically as well. GV-N660OC-2GD supports NVIDIA® 3D Vision™ Surround, so that users can easily experience broader and richer gaming environments. GV-N660OC-2GD brings games to life with NVIDIA® Surround; it also supports multi-monitor gaming environment with PhysX, 3D Vision and the unbeatable power of SLI.

PhysX Technology

NVIDIA® PhysX™ is the next big thing in gaming!Delivering physics in games is no easy task. It's an extremely compute-intensive environment based on a unique set of physics algorithms that require tremendous amounts of simultaneous mathematical and logical calculations. The best way to get real-time physics, such as explosions that cause dust and debris, characters with life-like motion or cloth that drapes and tears naturally is with an NVIDIA®PhysX™-ready GeForce® processor. PhysX software is widely adopted by over 150 games, is used by more than 10,000 registered users and is supported on Sony Playstation 3, Microsoft Xbox 360, Nintendo Wii and PC. PhysX™ technology will take gaming to a whole new level.

CUDA Technology

NVIDIA® CUDA™ technology unlocks the power of the hundreds of cores in your NVIDIA® GeForce® graphics processor (GPU) to accelerate some of the most performance hungry computing applications. The CUDA™ technology already adopted by thousands of programers to speed up those performance hungry computing applications.

SLI™ Technology

Delivers up to 2X the performance of a single GPU configuration for unparalleled gaming experiences by allowing two graphics cards to run in parallel. The must-have feature for performance PCI Express graphics, SLI dramatically scales performance on 60 top PC games.

NVIDIA® 3D Vision™

NVIDIA® 3D Vision™ brings a fully immersive stereoscopic 3D experience to the PC. A combination of high-tech wireless glasses and advanced software 3D Vision transforms hundreds of PC games into full stereoscopic 3D. Users can even watch 3D movies and 3D digital photographs in crystal-clear quality.

Microsoft Window7

Microsoft Windows 7 is the next generation operating system that will mark a dramatic improvement in the way the OS takes advantage of the graphics processing unit (GPU) to provide a more compelling user experience. By taking advangate of the GPU for both graphics and computing, Windows 7 will not only make todays's PCs more visual and more interactive but also ensure that they have the speed and responsiveness customers want
