Alienware unleashes four-GPU monster

The high-performance PC maker claims that CrossFireX is the first quad-GPU gaming platform to support DirectX 10.1.

The PC uses two ATI Radeon HD 3870 X2 graphics cards, each housing two GPUs and a full 1GB of dedicated graphics memory, making 2GB of dedicated GDDR3 graphics memory.

"Alienware is extreme high-performance PC gaming, and expectations are never higher than when dealing with the ALX CrossFireX, our most sophisticated desktop system," said Brian Joyce, senior vice president at Alienware.

ATI's Catalyst software allows users to 'unlock' the GPU controls to manually set the engine and memory clocks for overclocking and performance boosts.

Temperature displays and VPU recover safety features make it easier to maintain the system, while an auto-configure utility option overclocks to a preset stable speed.

Rick Bergman, senior vice president at AMD's Graphics Product Group, said: "CrossFireX allows for more immersive gaming than before, giving gamers the ability to play at high resolutions and settings with great performance."

The ALX CrossfireX is available from £3,557.
