Can I SLI 2 different models of the EVGA GTX 680?

Basically I wanted to add another 680 to my machine. I currently have a EVGA GTX 680 SC 2GB signature+. However I have been finding it difficult to find this model anywhere. Would I be able to SLI it with a different model such as the 2GB signature2?

  1. Yes. However if for some reason one card is faster then the other due to overclocks or has more vram, both will default to the lowest common denominator.

    Yes, it will work fine. I myself have a EVGA GTX 680 FTW+ 4GB and a EVGA GTX 680 Superclocked+ 4GB in SLI and I just clocked both cards the same down to the VRAM and core and such. It works great and I even have both cards underwater on the same loop with no issues. :)
