System requirements and recommendations:

  • PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
  • 750W (or greater) power supply with two 150W 8-pin PCI Express power connectors recommended
    • 1000W (or greater) power supply with four 150W 8-pin PCI Express power connectors recommended for AMD CrossFire™ technology in dual mode.
    • NOTE: Minimum recommended system power supply wattage is based on the specific graphics card and the typical power requirements of other system components. Your system may require more or less power. OEM and other pre-assembled PCs may have different power requirements.
  • The operation of AMD CrossFire™ technology in dual mode requires a second AMD Radeon™ HD 7990 graphics card and an AMD CrossFire™ Ready motherboard.
  • Minimum 4GB of system memory
    • 8GB (or more) system memory recommended for AMD CrossFire™ technology
  • Installation software requires CD-ROM drive
  • DVD playback requires DVD drive
  • Blu-ray™ playback requires Blu-ray drive
  • Windows Vista®, Windows® 7 or Windows® 8 operating system. 64-bit operating system highly recommended.
  • Use of 3 or more displays with AMD Eyefinity technology requires a DisplayPort-capable panel or an AMD Eyefinity validated dongle. See for a list of validated DisplayPort dongles
