I am actually very impressed with this idea:
Basically, every new (the 7xxa line at least) nvidia chipset based motherboard will come with integrated graphics. The IGP will be powerful enough to handle Aero, I assume, with very low power consumption. This is called the mGPU. While you are not gaming or doing any discrete graphics this is the only GPU being powered.
Sitting idle and unpowered in your x16 PCIe 2.0 slots will be you dGPUs (discrete GPUs) for gaming. Fire up a D3D or OpenGL game are you gaming card(s) fire up to work with your mGPU to play the game.
The benefit is obvious...power consumption. nvidia claims that this setup can save up to 400 W of power consumption (for high end 3-ways no doubt) at idle alone. They had talked about this a long time ago for notebooks, but it's nice to see this come to the desktop platform as well. This technology will make gaming laptops have an actual battery life since the dGPU(s) inside can be turned off (assuming they will release a notebook platform).
This makes me want to buy one just for the power saving alone with I upgrade later this year. Nice work, nvidia.
