CrossFire uses proprietary ATI software and a dedicated logic board in each graphics card to render the on-screen graphics or display using two cards with parallel processing, this can increase performance in games or video editing by a wide margin.
Current CrossFire configurations use a ribbon-like connector attached at the top of each graphics card inside the computer to allow communication and data transfer between the two cards.
To use CrossFireX, you need a CrossFireX certified motherboard and CrossFireX Capable graphics cards. It is also necessary to have a power supply capable of supporting the graphics cards.
