I need to save electricity as much as possible. But without losing the power when needed. Hope this is understandable and not a silly thing So I am trying to get the same switchable video cards found in laptops. I've enabled the IGPU in BIOS, with the Nvidia GT 520 inside. And using both inputs to my monitor, each one for each video card. Now as expected, Windows detect both video cards and both of them output video. And the question is: Is there a way to implement switchable GPUs here the same or similar way laptops do? Thanks.
