Haswell - Onboard Graphics and Video Card to Use 3 Monitors

From searching the forums, it appears that support for the use of onboard video and a graphics card at the same time is inconsistent among boards. Is this still an issue with Haswell?

I am trying to set up a 3-monitor system and was considering a Gigabyte motherboard (http://www.newegg.com/Product/Product.aspx?Item=N82E16813128667), but in the manual it only talks about turning onboard video on/off and doesn't address using both graphics sources simultaneously.

If someone would recommend another cheap (under $80) mobo that would would do this with certainty, I am all ears. Also, is there an easy to know if a Haswell-based mobo will do this? Thanks!

There is Bios option in some bios's that allows simultaneous use of the onboard GPU and discrete graphics card I can't remember what it is called exactly. (About to go somewhere don't have the time to look) a Quick google search allowed me to find this : http://www.intel.com/content/www/us/en/intelligent-systems/intel-embedded-media-and-graphics-driver/hybrid-multi-monitor-support-paper.html

I have actually done this myself when the HDMI on my GPU died and I needed a second monitor.
Err from what I know you can't use your onboard iGPU with your discrete card simultaneously. I am aware you can use an AMD APU and a discrete AMD card at the same time though but I don't think intel can do the same. But what I'm 100% sure you can do, is that you can use a two graphics cards to support multiple monitors. They don't have to be the same model or have to be in SLI. I know many people that own a card like a GTX 680 and use a dirt cheap GT 610 for use with extra monitors.
 
Yes - you can't use both integrated and discrete graphics at the same time. Like trying to sli 2 different cards.

If you have a decent graphics card it wouldn't make any difference anyway.

Even AMD can only use both at once for weak graphics cards eg r7 240
