How to switch between I-GPU and GPU without restarting the PC

hi , im using a i3-3220 3.3 ghz , included Intel HD graphics 2500 , but for gaming problems , im thinking about buying a dedicated GPU for gaming , but i still wanna keep using Intel HD graphics at times while working , because it consumes less power , 5W if i remember it right , so ... is there anyway i can switch it without having to restart the PC and mess with BIOS or un-plug and re-plug the cable everytime ? i can live with 2 monitor cable plugged in my PC though , but idk if there is a way to switch between 2 of em

As far as I know, (on a standard desktop PC), there is no way to switch without rebooting and getting into BIOS.

Some newer laptops have a switch, either hardware or software, that lets you do this, but I've never seen it on a standard PC.

Hook up the IGPU to one monitor, and the dedicated gpu to another. Simply disable the dedicated gpu in device manager when you only want to use the IGPU.

Even if you could, your discrete card is still gonna be drawing power, using the fan etc.

The whole purpose of a dedicated gpu is to take the work load off the cpu, so it can do a better job.

But you could give Doug`s idea a try. Do you have a way to measure the difference in power consumption ?

Power consumption on modern graphics cards at idle is a non-factor. Here is what the top end AMD and Nvidia cards use at idle,
