Alienware now offers the just announced ATI Radeon HD 4870 X2, the world’s most powerful graphics card, on its award-winning line of desktops, including the Alienware Area-51, Area-51 ALX and Aurora.
The ATI Radeon HD 4870 X2 features 2.4 teraflops of graphics power, 1,600 stream processing units, 2GB of dedicated GDDR5 memory and more for uncanny performance in PC gaming and HD video playback.
Hardcore gamers can take advantage of a full 2GB of GDDR5 memory, the fastest memory technology available today, for higher speeds, increased bandwidth and ultra-high frame rates. DirectX 10.1 support, along with high-performance anisotropic filtering and 24X custom filter anti-aliasing, delivers some of the most lifelike graphics ever seen. Environments, backgrounds and even facial features appear more true-to-life while deep background images gain heightened clarity so gamers can identify and target enemies at greater distances and with greater accuracy. For double the performance, all three Alienware desktops support dual ATI Radeon HD 4870 X2 cards in an ATI CrossFireX configuration for superior quad-graphics power.

Entertainment enthusiasts have dramatic new tools at their disposal for experiencing and enjoying HD content. Blu-ray movies play in full 1080p, while HD games and other media display at resolutions up to 2560 x 1600. The ATI Radeon HD 4870 X2 even features Enhanced DVD Upscaling, which allows users to watch standard-definition DVDs at near high-definition quality.
