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.
