    A good quality 750w for crossfired HD4870s to keep PSU at about 60% of rated power at load (recommended by PSU manufacturers)
    Corsair or PC Power and Cooling
  2. antec eartwatt 500 or 650.
  3. Thanks for help

    Just to let you know that AMD X2 will strangle a single 4870. Two of them :pfff:
  6. An OC'd 6000+ or higher would be fine.
  7. Get a 750TX from newegg, that should handle HD 4870 CF all right.

    IIRC the K9AGM2 has a single PCI-E x16 slot. I'm too lazy to check now, it's midnight here. If that's right, get yourself a K9A2 Platinum 790FX when you buy the second card. That MB does Crossfire at x16+x16 on both slots.
  8. What if i OC my cpu to 2.8 - 3.0GHz.. will it still bottleneck the 4870 then?
  9. Yes, but I don't think it will be too major with just 1 4870, but 2 would produce some definite bottlenecking. I recommend upgrading soon, once the new Deneb CPUs are out the X2s should fall in price so that would be a good time to upgrade.
