I think you can but your 680 will down clock to 670 speeds. I'd say SLI 680's or don't bother.

No he cant. Only ATI is generous enough to let you Xfire different cards.

I don't really have a problem with that, cause performance is near identical, I just want to use my 680 for single gpu games (Team Fortress 2), and sli for multi-gpu (arma 2 DayZ mod).

Any confirmed answers? I'm coming from ATI 7970's and 7950's that can do this, but I don't know much about nvidia.

No you can only SLI cards with the same GPU.

they do have the same GPU doh.gif

Just that the 670 has 1 smx unit disabled so less cuda cores... but same VRAM, bit rate , and other stuff...

I doubt that it will be possible tho

lol, but what you say makes sense, and theoretically it should work, except nvidia probably keeps it from happening at the driver level.

Not really...from what i have seen the disabled SMX units on the 670s are lazer cut and NOT software disabled like on the 6950s were biggrin.gif
