Can I quad crossfire 2x 5870 and 2x4870? benefits?

I am in the process of updating my system. I have 2 5870's that I am planning on crossfiring, but I also have 2x 4870's from my old setup. Is it possible to Tri or quad fire these? Would there be any performance increase?

More info:
New system:
ASUS crosshair iv formula
2x Sapphire 5870 (cypress xt) Pci-e 2.0 x16
4x 1gb DDR3 1800
AMD phenom 2 x6 1090t

Old Video cards:
2x Asus dark knight 1gb 4870's Pci-e 2.0 x16

Thanks!

  1. No you cant do that they need to be the same family and generation. So 48xx +48xx or 58xx + 58xx not 57xx+58xx

    Mactronix
  2. nope.
  3. might be possible with an msi lucid hydra board like

    but i don' t think they make one for more than 3 cards so might have to leave one out

    I would think different vendors as you can mix Nvidia and AMD cards together.
  5. Macronix is correct. A Radeon HD 4870 can only be crossfired with a 4830, 4850, 4870 or 4890. You're just going to have to have 2 awesome gaming systems instead of one. Personally, I'm just blown away by my Radeon HD 4870 1GB Quad-Crossfire setup. It's the most incredible thing I've ever seen! :D
