    For a 4.1/5.1 machines - is it possible to run the standard HD5770 and a GTX970/980/980ti at the same time? Each card would be hooked to a different monitor. The nvidia web drivers would be loaded. Assume the power is sufficient.

    a. I would hook the HD5770 to a low-end monitor for web browsing and productivity work. I should be able to see the boot screen right?

    b. and the GTX card would be for my Photoshop/Lightroom and FinalCutPro work. The GTX monitor would be 4k and color calibrated.

    What is stopping someone from doing this?

    People mix cards and brands all the time. I haven't seen this exact combination of models, but I don't see anything stopping you from doing this.

    Keep in mind the card in slot 2 will also block slot 3, and the MP might run more loudly due to the additional fans and heat. There is the power requirement, but you're asserting that it won't be an issue.

    Nothing. I had a HD5770 for the bootscreen and a GTX 750Ti as the power horse. You shouldn't have trouble either in OS X or in Windows.
