The other day, we heard Nvidia was readying their dual GPU monster, the GTX 590 and today, we get a date from AMD saying that they will launch the Radeon HD 6990 on March 8. Nvidia is also planning on a March release for the GTX 590 but they haven't released any dates yet. The HD 6990 will consist of two Cayman GPUs on a single PCB so expect it to be long and power hungry. The two cores will most probably be bridged using a PLX chip. No word on pricing and availability yet but expect the cards to hit retail around April.
