AMD's big gun was shown as iTOC has pictures
of the AMD Radeon HD 6990
codenamed Antilles being shown off. This beast is a dual core GPU in a single card solution and yes, it is huge.
It's going to take a lot of power as the card needs 2 8-pin connectors, which I think is a first for video cards. I'm expecting two AMD Radeon HD 6970
GPUs on board and to just fly through any game that it comes across. Look for the card sometime in the first quarter of this year.
