Ultra Durable VGA™
Features & Benefits
GPU Temperature 5%~10% down
Ultra Durable VGA board provides dramatic cooling effect on lowering both GPU and memory temperature by doubling the copper inner layer of PCB. GIGABYTE Ultra Durable VGA can lower GPU temperature by 5% to 10%.
Overclocking Capability 10%~30% Up
Ultra Durable VGA board reduces voltage ripples in normal and transient state, thus effectively lowers noises and ensures higher overclocking capability. GIGABYTE Ultra Durable VGA graphic accelerators improve overclocking capability by 10% to 30%.
Power Switching Loss 10%~30% Down
Ultra Durable VGA board allows more bandwidth for electron passage and reduces circuit impedance. The less circuit impedance, the more stable flow of current and can effectively improve power efficiency. GIGABYTE Ultra Durable VGA can lower power switching loss by 10% to 30%.

WINDFORCETM 2X: Anti-turbulence Cooling
The special inclined dual fan design effectively minimizes the flow of turbulence between two fans and enhances heat dissipation of hot area right underneath each fan. By unique design, WINDFORCETM 2X even enlarges air channel on the graphics card vents and creates a more effective air flow system in chassis. This special design helps heat dissipate quickly from GPU. In addition, WINDFORCETM 2X is equipped with 2 copper heat-pipes which strengthen the speed of heat dissipation.

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.

Windows Vista®
NVIDIA’s fourth-gereration GPU architecture built for Windows Vista gives users the best possible experience with the Windows Aero 3D graphical user interface.
Shader Model 5.0
Shader Model 5.0 adds support for indexed temporaries which can be quite useful for certain tasks.Regular direct temporary access is preferable is most cases. One reason is that indexed temporaries are hard to optimize. The shader optimizer may not be able to identify optimizations across indexed accesses that could otherwise have been detected. Furthermore, indexed temporaries tend to increase register pressure a lot. An ordinary shader that contains for instance a few dozen variables will seldom consume a few dozen temporaries in the end but is likely to be optimized down to a handful depending on what the shader does. This is because the shader optimizer can easily track all variables and reuse registers. This is typically not possible for indexed temporaries, thus the register pressure of the shader may increase dramatically. This could be detrimental to performance as it reduces the hardware’s ability to hide latencies.
OpenGL 4.0® Optimizations
Ensure top-notch compatibility and performance for all OpenGL 4.0 application.

การ์ดตัวนี้จะดีไซด์ไม่เป็นไปตามมาตรฐานของ NVIDIA นะครับ ก็คือจากแรม 768MB 192-bit จะถูกเพิ่มเป็น 1,024MB 256-bit แทน และถูกเพิ่มความเร็วขึ้นมาอีกเล็กน้อยจาก 675/1,350/3,600MHz มาเป็น 715/1,430/3,600MHz นะครับ และหน้าถัดไปก็ไปชมตัวการ์ดกันต่อเลยครับ
