    Weird Question, Duel GPU's


    Just a weird question that just popped into my head.. Is it possible to run two GPU's that are not even remotely the same on one system? Like, be able to choose which one you want to use for what..? I'd say it would be a power thing, have the lower one in use while on general personal use, like email, web, ect.. And the big card for gaming, rendering, ect.. Is that a possibility?

    Yes, you can use multiple cards, each for multiple displays. That's why you see some Flight Simulator folks running 4+ monitors. But they will not work together to render one scene (also known as crossfire).

    Of course, you need the appropriate slots on your motherboard, each matching one of the video cards. Then there is the power issue. They both would always be 'on', hooked up to the monitor you want it to display on.

    There's plenty of references about how to do it. You may even find one referencing your motherboard.

    I suppose I need to simplify my question.. Two different GPU's on one monitor.. The ability to switch between the two for certain uses. Of course they won't work in crossfire/sli since they aren't remotely the same, and I'm not saying I'd want it to both run at the same time. I'm talking about one card running, one card off for simple stuff.. Then the other card on and that one off for heavier stuff like gaming and rendering..

    Your monitor would have to have two inputs. One of mine does and has ability to switch inputs manually (monitor control) or auto if it's set like that. I never tried doing it from 2 GPUs on same computer but used it with two computers. In the case of what you want to do, there would have to be a way to switch GPUs on the fly. In any case it would be really cumbersome.

    They make VGA switches.

    I'm a gamer, so VGA would be kinda pointless for me I was thinking more along the lines of software that allows an auto switch to a lower GPU while the main, bigger GPU is not needed. It's an on the fly question, I've got the R9-270 for my main and a spare HD-5450.. Thought it would have been cool to not only save power by having it switch to the lower one but also prolong the life of the bigger GPU by cutting down the amount of use. I think it's an interesting concept, but I've never seen or heard of it being done before. I think that would be cool to bring to life though since it would potentially extend the life of your gaming GPU's

    Laptops with dual graphics do that all the time. I don't think in this case you could achieve any significant power savings or wear and tear on GPU. Newer GPUs are scalable enough to use and to be used much less when all the power is not required.

    The increase in the longevity of the better card would be negligible at most. Despite switching your monitor to receive the output of the second card, the primary card would still be running. Cards use very little processing power when on the desktop and what not, and they already switch between 2D and 3D speeds etc, so are pretty optimised in powering down themselves.

    OK, a HDMI or DVI-D switch then.

    Still, seems a bit pointless as has already been said.

    EDIT: Got me searching. Boy, this one looks nice if I needed it: 2X1 Enhanced Powered DVI Switcher - Monoprice.com

    This is a dumb question but could you do SLI with a editing card and a gaming card
