I was switching between the two in BIOS (a cable attached to each), but somewhere along the line I started having a problem with that method, and was having various issues such as having to remove and replace the cable from the HD4000 output when booting into Windows or be stuck with a black screen (didn't matter which input the monitor selected - VGA for the HD or DVI for the AMD).
I've been switchintg via Device Manager since then (hotkey for Device manager). I was assuming this would create a minimum power state for the AMD card. The fans still run obviously, but not much else. CCC is not accessable, and the same is true with the HD4000 when it is disabled.
Sometimes Windows gets a bit confused and thinks I need to install drivers for the AMD, but for the most part it works better than rebooting and going through BIOS. The worst that happens is having to reboot - .
I'm wondering how much power I save though. I've read the 7000 series is very good with power at idle, and not much more than when using the HD4000 anyway, but hey ! This integrated thing is a new toy so I switch, just because I can.
Don't know about other games on my Steam account but when I forget to change and launch Skyrim I get a message that it is readjusting the settings down.
