Can I use the video card integrated into the i7, and also another, PCI Express video card? [duplicate]

How can I enable onboard graphics AND dedicated card simultaneously ?

I'm trying to make a 3-monitor system, with an Intel i7 Sandy bridge.

I'm looking at 2 options:

1. Get a P67 motherboard, and plug 2 video cards in it (2 DVI outputs each)
2. Get a H67 motherboard, plug 1 video card (2 DVI outputs), and use the integrated graphics in the CPU to power the mother-board integrated graphics card.

I read somewhere that if you plug in a video card, then the integrated graphics get disabled automatically. If this is true, then option 2 won't work.

So, will the CPU integrated graphic card work even if I plug in a regular PCI Express 2.0 video card?

Also, should I play games, will they use the much more powerful GPU? Or will they use the CPU graphics card?

Solution 1:

You read that right.

No, it will be switched off.

should I play games, will they use the much more powerful GPU? Or will they use the CPU graphics card?

Since only one can be active, the one which is currently in used will handle all graphics processing. Goes without saying, most newer games will require a discrete graphics card.
