Nvidia Graphics Card in Crossfire Motherboard?

[RobDMB]

Probably a dumb question, but can you use Nvidia graphics cards in an ati crossfire motherboard? Thanks, Rob

sure..u just cant use crossfire features.

Or SLI.

This is what I don't get.... PCI-express is standardized. What reason should there be preventing intercompatibility other than greed?

SLI / Xfire is not standardized... That's the problem.

Crossfire and SLI "about" the same from the concept that you are using 2 graphics adapters but the implementation is different.

But the way the PCI-express slots communicate with each other and the CPU should still indentical. So any chipset offering a two x8 PCI-e slot mode should be perfectly capable of running either SLI or Crossfire. I'd imagine the only thing prevent such operations is deliberate limitations introduced in software.

your right, there should be a way around it...

This is correct. SLI and Crossfire both work fine on Intel dual-PCIe motherboards, but ATI and NVIDIA have prevented cross-compatibility with each other's boards (at least for now). NVIDIA, in particular, has little to gain right now from allowing SLI to work on ATI's boards, since they have a bigger chunk of the AMD marketshare than ATI, and currently have the lead in terms of dual-GPU setups (though ATI is catching up somewhat as their availability gets better).
