Haswell on-board and discrete graphics simultaneously?

[chris_s]

For Haswell-based CPU and chipsets, is it possible to use the on-cpu graphics at the same time as a pci express graphics card?

For example, the main monitor being driven by the pci-e card, and a secondary monitor on the integrated graphics.

you would be better of getting a decent card and running both monitors off it. Unless you have hybrid graphics aviable you cant use onboard and card at same time.Easy enough to check go into bios and look at setting for graphics it should say onboard, pci-e, hybrid so if the hydrid isnt there you cant use both.

The thing is, I already have a decent card (Radeon HD 5770) but when I run two screens, in-game performance suffers due to AMD's crappy drivers.

Still can't find any proper information other than the hybrid graphics you mention being a feature of AMD chipsets.

My current motherboard (GA-EP45-DS3LR with core 2 quad) does not have integrated graphics but I will be upgrading when I find an answer to my question.

I use a 6970 and dont have any problems at all using 2 screens , now if i try to make a eyeinfinity group and play the game on both at the same time i get problems. That isnt video card drivers it is game devlopers not coding the game to be played that way.

I have a separate GPU that runs 2 monitors.  Can I also use iGPU of the CPU to run a third monitor at the same time?  Thanks!

Not usually. If you do a search some card are able to do it but i have found that it is a mid range card.
