ATI + Nvidia in SLI/Crossfire

I have an ATI HD Radeon 5800 series card.
If i add a Nvidia 400 series card to it, will these 2 puppies play nice?

Ive been looking to get another graphics card for a grand total of 2. The 480 coming out looks pretty sexy. I might end up just getting another 5800 series....but itd be nice to know the option is there to run a mix of an ati and an nvidia card in crossfire/sli mode.

  1. They wont play at all. You have two options running them independently for multiple monitors or use the GTX4xx as Physcx (way overkill)
  2. You can if you get a Lucid Hydra board. Though IIRC it doesn't scale all....

    You can't mix SLI and Xfore but you certainly can add an Nvidia card as a dedicated PhysX card. However, the 400 series is way way overkill for a dedicated PhysX card.,8786.html

    To see the difference a $65 (GT220) investment can make, see the video here:,2465-11.html

    Twin 5800's in Xfire and a GTS 250 would rock your world
  4. Thats the manufacturer of the chips.

    You would want a motherboard that features those chips. The only one out is the MSI Big Bang which is a P55.
  5. So if i throw in a nvidia card it will only work as a physx card?
  6. As others said you can't use an ATI card with a Nvidia card on a single board unless its Lucid Hydra board(which currently doesn't scale well as either SLI or CF)
    So if you want to use an ATI card with a Nvidia card,the Nvidia card will be used as a PhysX card
