According to latest news, first sample of AMD’s top notch graphics card, the two headed monster — Radeon HD 6990 (codename Antilles), has already arrived at reviews hands. This can only indicate that the official presentation of the graphics card is not far from now.

Apart from referenced design cards from AMD, we’ll most likely see some custom cooled solution from AMD’s partners presented the same day.AMD Radeon HD 6990 is expected to be have two Cayman-based GPUs , built using 40nm process logic, operating in CrossfireX mode. The performance configuration will feature slightly over 3K of Stream Processors while a total amount of high-speed GDDR5 memory will hit of 4GB number.
The set of output connectors will amount four Mini DisplayPorts, so support AMD Eyefinity technology and one DVI port. The latest DX11 flagship will will have one CrosfireX header to provide possibilities for Quad-GPU setups. As for power, it is confirmed to have two 8-pin power connectors which together with PCE-Express power specification can bring up-to 375W.
