ATI Radeon HD 4850 X2 graphics card, which was formally announced way back in August and is still unavailable, was spotted today over at pchacc.cn leading us to believe that it will finally hit the market for real. The card below is build by ATI's major partner Sapphire and features custom dual-slot cooling system, 2GB of GDDR3 memory, a 256-bit memory interface, CrossFireX support and blue PCB. Last but not least are the two 55nm RV770 GPUs and the GPU bridge that links them. The card will require an extra 6-pin and 8-pin PCIe connectors. Currently, there's no exact release date, but the little brother of 4870 X2 is expected to become available later next month.
