Sapphire has launched what it claims its the only graphics card you can get that features AMD's ATI Radeon HD 4850 X2 twin-GPU set-up.

Sapphire's HD 4850 X2: two GPUs, one supplier

The Sapphire HD 4850 X2's two 4850 chips each connect to its own 1GB of GDDR 3 memory over a 256-bit bus. Both GPUs co-operate using AMD's CrossFire technology, and if you've the right kind of motherboard, you can put two of these boys together for some four-way GPU-on-GPU action.

The two-slot card has a pair of fans to keep the GPUs cool, plus TV-out and four dual-link DVI ports.

Sapphire's pricing the HD 4850 X2 at $419 - around £317 over here - and it'll go on sale any day now.
