I'm planning on buying a new computer with the following motherboard: ASUS P8Z77-M Pro. Can the integrated graphics be combined with the video card mentioned above? Or are the on-board graphics automatically switched off when I plug in the video card?
Yes you can use both combined or independently with virtu. Or use them both independently with multiple monitors (this is what I do). You can set it to 32MB so eating ram is not something to worry about.
