  1. Best answer
    Even if you could crossfire a 7850 with a 7790, it would just downclock itself to match the 7790. Don't waste the money and just grab another 7790.
  2. Okay thanks, do i need upgrade my power supply?
  3. Depends. 1) Does it have two PCIe connectors?
    2) What brand and model is it?
  4. 1) only one
    2) cooler master - 460 watt
  5. Then you're going to need an upgrade, yes.

    You need a power supply with two PCIe connectors, and one that's relaible; cooler master isn't.

    I'd recommend a 500 or 550w by corsair, seasonic, or xfx.
  6. Thanks bro. gonna find some money now.
