Hello everyone,

Let's say that I have a computer with these components:
motherboard: Asrock Z97 Extreme4
processor: Intel Core i5-4690S
grahics card 1: SAPPHIRE R9 280X DUAL-X
grahics card 2: EVGA GeForce GTX970 FTW ACX 2.0

Will I able to a use both dedicated gpus and intel integrated gpu at the same time with this setup (I mean utilizing all three cards in one computation in parallel at the same time) ?

I want to have access to CUDA, Mantle and other vendor specific features under one roof (therefore this weird combination of all platforms).
Also, I plan to write my own software in OpenCL that will run on this hardware, therefore I don't care whether there is any software that can make use of such setup.
So I am interested in this question from HW point of view (and possibly from the point of view of drivers and their compatibility) rather than SW point of view.

I assume the answer is yes, but I want to make sure, before making any decisions.
If you think this configuration will not work, but in general it should be possible, please suggest another one.

Thanks in advance for your responses.

What do you mean by cross interface compatibility ?

I know that the Intel GPU is not awesome. I would not buy it on its own, but it comes with the processor anyway, so why not utilize it by offloading some small percent of computation on it.

I only want to know whether the motherboard I mentioned will allow me to use Intel GPU together with some dedicated GPU.
According to this webpage: http://superuser.com/questions/241157/how-can-i-enable-onboard-graphics-and-dedicated-card-simultaneously it should be possible as long as both the processor and the motherboard chipset support Flexible Display Interface. From what I read this is supported since Sandy Bridge processors and chipsets H67, Z68 (probably).

However on my notebook (Acer TimelineX) which has a Sandy Bridge processor (don't know the chipset), I seem to only be able to use switchable graphics, therefore I would really appreciate an answer from someone with experience.

I still dont know why there arent any GPU from Intel like AMD has? If the rendering part is mostly done on the CPU then whats the problem to create GPU? INTEL are u listening?
