AMD Radeon™ HD 6990

The XFX Radeon™ HD 6990 creates the ultimate in intense, immersive HD gaming with raw performance, Dual GPU, 4 GB GDDR5 high-speed memory and an impressive array of ground-breaking features, giving even the most hardcore gamers an extra boost of adrenaline to take the game to the next level.

Immerse yourself with the XFX Radeon™ HD 6990 enabling DirectX 11 gaming on up to four simultaneous displays utilizing up to four Mini-DisplayPort 1.2 outputs, as well as Stereoscopic 3D gaming and Blu-ray 3D playback with AMD HD3D technology – all from a single graphics card.

In addition, AMD’s exclusive anti-aliasing platform, Morphological Anti-Aliasing (MLAA), reduces and smoothes jagged lines to enhance visual qualities without lowering frame rates associated with standard anti-aliasing. Not all games have anti-aliasing support, but MLAA can enhance your graphics on any application.
