I will probably wait for the 880 to come out but I was just wondering if anyone had already done this. Can I put these two GPUs in the same PC? If I have to switch them out everytime then I wonder if I can do that without restarting? Or maybe I can put them in 2 different slots on the motherboard and switch the cables to the other one when I want to use the other one? Maybe I should instead put the 780 to connect to one monitor and the K4k to connect to the other one? Anyone that knows if this will work or has a good educated guess plz answer I'm waiting ur reply.
