These days, it's not enough to have just one GPU. Sometimes you need to have a couple video cards in your system. But to be even cooler, you need to have multiple GPUs on the same card.
AlienBabelTech has images of a mystery card from ATI that features 1440 stream processors, pointing to the Radeon HD 5850. The card is believed to be the HD 5950, or perhaps the HD 5850-X2.
