SLI? GPU Question

I am very confused about a specific GPU.
I am about to get a laptop and the NVIDIA GeForce GT 750M 42GB GDDR5 keeps showing in a great deal of good deals :)

First, I don't see this card listed in the System Requirements by Adobe here
So Im assuming No for Ray-tracing Yey for Open GL?
My hunch is positive about this card, I also see that this is the cars that is coming with macbook nowadays...

The next question im confused about is:
Would I benefit anything from heaving a
Dual (2x) NVIDIA GeForce GT 750M SLI 2GB GDDR5?

Thank you for any info!
I know these question were probably asked many many times. I could not find specific answers the there 2 questions?
Is the card happy with AE?
Will SLI be happy with AE?

> "So Im assuming No for Ray-tracing Yey for Open GL?"

That sentence shows a couple of misunderstandings.

First, the GPU acceleration of the ray-traced 3D renderer in After Effects has nothing at all to do with OpenGL. It depends on CUDA. OpenGL and CUDA are two extremely different GPU technologies, for very different things.

Second, the absence of a card on our list of tested and supported cards means just that: the card isn't tested and supported.

Read these two pages carefully:

There's also an explicit answer there to your question about multiple GPUs. (summary: yes)

Hi Todd,

I know you answer alot of questions about GPU and Ray Traced 3D. I looked over these links and I don't see the answer to my specific question. If I have two GPU's (GeForce GTX 760's), is it better to run them SLI or just have both installed? If it's not SLI will After Effects, Premiere, and Media Encoder put the second card to use during rendering? And lastly, is the second card only used during rendering, with no playback improvement or RAM preview improvement?

Oh, and I'm not really using the Raytraced render engine, so if I'm not is there really any benefit to having the second card?
