SLI/Crossfire diffrent model cards

So the other day I was thinking, for my if I bought a GTX 1660ti and a 2080ti and SLI'd them together what would happen. Has anyone done this?

You can't SLI different models. The 1660Ti doesn't support SLI at all.

You can't SLI two different chips. Besides, you can't even SLI 1660 Ti's together.

@Spotty already answered that. The other part to using multiple GPUs is that low level features of DX12 and Vulkan allow for custom handling of multiple various GPUs but that has to be codded into the game itself and usually it's not worth it as market share of multi-GPU gaming PCs is close to zero. I've see like one game only advertising support for DX12 multi-gpu (non-SLI, non-Crossfire).

 

In some GPU computational apps multiple GPUs could be used but that's a different story.

Not possible.

 

Also, SLI and Crossfire aren't worth it (at least for gaming). So few games support it that it's not worth the added cost, and you might end up with more bugs or worse performance because of it as well, since some games react really poorly to SLI and/or Crossfire.

Go ahead and buy them.
