A multi-GPU interface from ATI for connecting two ATI graphics cards (display adapters) together for faster rendering on one monitor. CrossFire machines require PCI Express slots, a CrossFire-enabled motherboard and, depending on which models are used, either a pair of ATI Radeon cards or one card and one matching CrossFire Edition card. A four-card system (Quad CrossFire) doubles the processing capability. See
