- Longer Life – All-Solid Capacitor Design
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.
AMD Eyefinity
Supporting multiple independent display outputs simultaneously, AMD Eyefinity technology delivers innovative graphics display capabilities enabling massive desktop workspaces and ultra-immersive visual environments for the ultimate panoramic computing experience.
AMD EyeSpeed technology helps you:
■Enjoy beautifully rich and clear video playback when streaming from the web
■Take in your favorite movies in stunning, stutter-free HD quality
■Run multiple applications smoothly at maximum speed
■Enjoy lightning fast game play and realistic physics effects
Cross Fire™
Multiply and Conquer with Multi-GPU Performance:CrossFire’s “supertiling” GPU sharing speeds rendering by evenly dividing the graphics processing, intelligently alternating the rendering workload to each Radeon GPU for efficient load balancing, and optimized performance.CrossFire boosts image quality along with rendering speed, eliminating the need to crank down screen resolutions to get the high image quality you want.CrossFire supports a wide range of ATI-based graphics cards and motherboards, and offers compatibility with a broad array of third party components for a flexible and robust solution.
Avivo™ HD
Avivo™could provide vibrant high fidelity, flawlessly smooth next-generation video playback. Avivo™ technology easily allows your PCs to become digital home media center by its compelling video pipeline design that comprises the latest high definition video hardware acceleration, including H.264 and WMV9.
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

I’m not entirely certain the Gigabyte.us spec list is 100% accurate, as to the best of my knowledge the entire AMD HD 7xxx series is PCIe 3.0 rather than 2.1. PCIe is fully forwards and backwards compatible, so you can run this PCie 3.0 card in any PCIe slot you have, even an old 1.0 slot. That is the only dubious looking info though.
Notably lacking from the spec sheet is the number of cores, 640 in the case of this 7770.
Next we’ll check out some pictures, and then finally benchmarks!
