GA-Z77X-UD3H - Can I Use Both Onboard Graphics & Graphics Card?

[hcour]

I'm building a new system with this board. I have a nVIDIA GeForce 8600 GT video card w/512mb memory that I'll be using from my old system. I have two monitors. Two questions:

Can I plug one monitor into the onboard video and one into my video card?

Providing I can do this, would it give better performance? That is, would it be worthwhile to do it? Or would it be better to just plug both monitors into the video card?

Thanks.

Hi hcour, 

What is your CPU?

In wait time, try with your graphic card. Normaly is the best.

If you use a Integrated graphic processor... you use a second drivers... drivers for IGP.

Hi hcour,

I see:
Intel® Core™ i5-3470 Processor
(6M Cache, up to 3.60 GHz)
http://ark.intel.com/products/68316/

Processor Graphics    Intel® HD Graphics 2500  (IGP)
Graphics Base Frequency    650 MHz
Graphics Max Dynamic Frequency    1.1 GHz

I think the best is use the graphic card.
But if you want try one monitor to IGP and other monitor to graphic card.
Why not... just install drivers for IGP
Check setting in Bios and Windows...
