 | Ultra Durable 2
Using high quality components on graphics cards is the key factor for having a long lasting, stable and reliable product. GIGABYTE is again setting a new standard by using Ferrite Core Chokes, Low RDS (on) MOSFET and Lower ESR Solid Capacitors, providing the stability and reliability from their high-end graphics solution. In addition, GIGABYTE Ultra Durable 2 Edition graphics cards now feature a sophisticated layout topology. This state-of-the-art power design from GIGABYTE delivers the ideal integration of thermal, electric characteristics, digital signals, power circuitry and optimum placement of components for enhanced graphics performance. |
 | Gold plated HDMI
Gold plated, durable large contact area connectors have been used for optimum signal transfer between connections |
 | GIGABYTE custom-designed 10 cm cooler
As opposed to the stereotype, GIGABYTE is able to maximize fan size to 10cm with the latest cooling design. With a 10cm fan, the card is virtually silent that its noise level runs much lower |
 | NVIDIA GeForce Experience
Want to know the best settings to play your games? GeForce Experience will figure it out for you. GeForce Experience connects you to NVIDIA’s cloud datacenter to download optimal game settings tailored to your PC based on your CPU, GPU and monitor. Optimal settings maximize image quality while maintaining great performance so you get the best experience. A built-in interactive screenshot viewer helps you learn more about each setting and their benefits. The GeForce Experience application automatically notifies you of new driver releases from NVIDIA. With a single click, you’ll be able to update the driver directly, without leaving your desktop. |
 | NVIDIA Kepler GPU Architecture
NVIDIA's Kepler GPU architecture has been designed from the ground up not just for maximum performance in the latest DirectX 11 games, but optimal performance per watt. The new SMX streaming multiprocessor is twice as efficient as the prior generation and the new geometry engine draws triangles twice as fast. The result is world class performance and the highest image quality in an elegant and power efficient graphics card. |
 | NVIDIA Adaptive V-Sync Technology
Nothing is more distracting than framerate stuttering and screen tearing. The first tends to occur when framerates are low, the second when framerates are high. Adaptive V-Sync is a smarter way to render frames. At high framerates, V-sync is enabled to eliminate tearing, at low frame rates, it's disabled to minimize stuttering. It gets rid of distractions so you can get on with gaming. |
 | NVIDIA PhysX Technology
PhysX is designed specifically for hardware acceleration by powerful processors with hundreds of cores. Combined with the tremendous parallel processing capability of the GPU, PhysX will provide an exponential increase in physics processing power and will take gaming to a new level delivering rich, immersive physical gaming environments. |
 | NVIDIA CUDA Technology
NVIDIA CUDA technology is the world’s only C language environment that enables programmers and developers to write software to solve complex computational problems in a fraction of the time by tapping into the many-core parallel processing power of GPUs. With millions of CUDA-capable GPUs already deployed, thousands of software programmers are already using the free CUDA software tools to accelerate applications—from video and audio encoding to oil and gas exploration, product design, medical imaging, and scientific research. |
| NVIDIA Surround with up to 4 Monitors
Nothing is as breathtaking as playing your favorite games across three monitors. At 5760 x 1080, the expanded field of view fully engages human peripheral vision and provides for the most immersive experience in racing and flight simulators. Add in a fourth display to keep tabs on chat, email or web while you are gaming. |
 | 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. Get up to 2x monitor and keyboard brightness with NVIDIA 3D LightBoost technology. In addition, you can enjoy 3D movies and 3D digital photographs from 3DVisionLive.com in eye popping, crystal-clear quality. |
 | NVIDIA PureVideo HD Technology
Blu-ray and HD DVD movies are bringing a new level of movie-viewing experience; with high-definition image quality far surpassing standard-definition DVDs. NVIDIA PureVideo HD2 technology provides unsurpassed Blu-ray and HD DVD movie picture quality. |

Most tech reviewers have given it the thumbs down, not realising the card downclocks if it heats up because of its low default fan speed {48%}. Changing the fan setting from default auto to manual and increasing the fan speed to over 70% will, in my experience, prevent downclocking. When the card runs at full speed, it eaquals and betters its rival AMD 7750.
