right now I have a 760 windforce with which I'm more than happy but the 780 poseidon looks soooo sick I'm thinking of getting it which is a big maybe and I want to keep the 760 too is there anyway that I can use them both? I know sli is not possible I just want to know if i can use them from the same pc maybe one at a time. I just want to know might not even buy the 780. thanks
