Overclock Edition
GIGABYTE GV-R785OC-2GD is an Overclock Edition Graphics Card. Not only built with AMD’s latest 28nm GPU and GDDR5, GIGABYTE overclocks these cards to provide end users an incredibly immersive HD gaming experience and unrivaled performance.

GIGABYTE always dedicates to providing the best thermal solution for serious gamers.GV-R787OC-2GD features WINDFORCE™3X Cooling Technology, GIGABYTE’s innovative new generation triple-fan solution with patented anti-turbulence inclined fans 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. For GV-R787OC-2GD, GIGABYTE creates the first unique "Triangle Cool" Technology (patent pending) to enhance the speed of heat dissipation.

GV-R785OC-2GD features two 100mm inclined fans and two pure copper heat pipes. With 100mm fans, the card is virtually silent that its noise level runs 31dB at full loading. Each fan has 30.5 CFM airflow to enhance heat dissipation. With king-size fans and inclined fan design, heat can dissipate quickly by the most effective airflow. New WINDFORCETM 2X also adapts Direct Heat Pipe Touch technology, which means that heat pipes physically contact with GPU directly. Processor’s heat will transfer to heat pipes and fins.

AMD CrossFire™ Technology
The AMD Radeon™ HD 7870 GPU supports AMD CrossFire™ Technology and provides excellent multi GPU scaling. With the introduction of the AMD Radeon™ HD 6900 Series Graphics, AMD began delivering improved AMD CrossFire™ Technology scaling when using two GPUs. AMD is proud to continue to offer that amazing performance with its newest AMD Radeon™ HD 7000 series graphics products.

AMD Eyefinity Technology
AMD Eyefinity Technology provides advanced multiple monitor technology enabling an incredibly immersive graphic and computing experience with innovative display capabilities, supporting massive desktop workspaces and super-high resolution gaming environments. AMD Eyefinity technology with DisplayPort connectivity enables a single GPU to support up to six independent display outputs simultaneously, depending on the OEM implementation.
AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, one of two cases must be satisfied:

1) Additional panels with native DisplayPort™ connectors are used;
2) Certified DisplayPort™ adapters to convert your monitor’s native input to your cards

DisplayPort™ or Mini-DisplayPort™ connector(s) are used.
With the introduction and wide availability of DisplayPort™ to single-link DVI dongles, option 2 above is a low cost way to convert a set of already-owned monitors into an AMD Eyefinity technology ready display configuration.

Unlike a similar multi monitor gaming solution offered by NVIDIA, AMD Eyefinity technology does not require two graphics cards to work. Therefore, AMD offers a multi monitor gaming solution with potential for a lower setup cost. A single AMD Radeon™ 7970 GPUs can employ AMD Eyefinity technology and AMD CrossFire™ technology to provide an outstanding multi monitor gaming experience. The following chart shows the AMD Radeon™ HD 7970 graphics in a dual AMD CrossFire™ configuration versus the NVIDIA SLI GTX 580 in three monitor gaming scenario’s.

Improved Tessellation
The latest iteration of architecture in the AMD Radeon™ HD 7970 GPU features a brand new Generation of Tesselator (Gen 9) in its Geometry Engine. This features optimizations such as; Increased vertex re-use, Off-chip buffering improvements and larger parameter caches. This helps Improve performance at all tessellation factors at up to 4x the throughput of AMD Radeon™ HD 6900 series graphics (Gen 8 ).

AMD HD3D Technology
AMD HD3D Technology is supported by an advanced and open ecosystem that, in conjunction with specific AMD hardware and software technologies, enables 3D display capabilities for many PC applications and experiences.

Your PC has evolved, offering unprecedented amount of games, photos and movies for you to play, watch, design, create, share and download in 3D. With the arrival of the latest in 3D technology you can now enjoy an enhanced visual experience on Stereo 3D-capable desktops and notebooks powered by AMD HD3D Technology.

HDMI 1.4a
More bandwith than standard HDMI allows full implementation of 60Hz Stereo 3D. Standard HDMI ports do not have adequate bandwidth for more than 3D 1080p at 24fps.

Ultra-high resolution (4k Panels)
- Current implementations currently use 4*DVI or 2*DP 1.1, which is expensive and unwieldy.
- AMD will move to a single-connector output for 4k via DP 1.2 HBR2 and HDMI 1.4a 3GHz mode.

AMD Quad Buffer SDK
- Native 3D support for Developers.
- functions with Dx9, 10 and 11
- Native support scheduled for Windows 8
Nearly 600 games support AMD's implementation of 3D either natively or through middleware partners. Also support for many 3D displays already on the market including Samsung and LG's proprietry implementation.

Video Codec Engine (VCE)
- H.264 HD Encoder
- Power efficient
- faster than realtime 1080p @ 60 FPS
- Variable Compression Quality
- Multiple Input Options:- (1) Frame Buffer, (2) GPU Display. (2) is useful for wireless displays.
