Gtx690 vs 780Ti workstation

So I have been racking my brain over choosing between the 690 and 780 Ti for my workstation.

CURRENT SET UP
Asus X99 Pro
5820k
8 GB Team 2400 DDR4 RAM
MSI R9 360
250GB HDD (OS , programs)
1 TB HDD (storage)
4TB HDD external (archive)

Next purchases will be--
64GB 2133 Crucial Value RAM
SAMSUNG sm951 m.2 SSD (OS, programs)
ADATA 256 SSD 2x in RAID O (working data)

GTX960 or 780ti<

Im using Photoshop, Premiere and After Effects as well as CAD and comp software. I use the Ray Trace Engine in AE alot and do a lot of 3d.

Ive read Tomshardware review of graphics cards for workstationsas well as studio 1. Ive found as many youtube videos regarding rendering and encoding regarding these cards as well as simulations. I am well aware of quadro and firepro being suited best for some apps.

I dont game so that is not a factor in this decision.

I like the 690 because it is dual CPU (to which I understand AE will only see one GPU)

I like the 780ti for its CUDA and bandwith.

I know SLI is always an option for the future.

Both cards will be used, not new. And both are the same price range.

Any links would be helpful.,

Any content creator opinions are welcome...

What GPU would you buy to complete the above set up?

What version of Creative Suit are you using, or is it CC? And what CAD packages are you using?

Using CC 2015 heavily

CATIA V6, solidworks

Did you ever consider FirePro or Quadro?

CC can use both Nvidia and AMD cards for acceleration, and I think Autodesk stuff can, too.

Solidworks doesn't really take advantage of a GPU, unless it's a workstation card. Don't know about Catia.

690 isn't worth it, IMO. GTX 970 is on a par with 790 Ti performance, so I'd say 780 Ti, 970, or R9 390. If you're not gaming, do what @CrossCarbon said, and look into FirePro or Quadro cards.

Why 780 Ti vs 690? Getting them cheap?

From my experience in AE the Radeon R9 360 doesnt ray trace and I use that function a lot, so I need NVIDIA CUDA for that.

Solidworks does require a certified card like a Quadro or Firepro, this I know. I did consider a Quadro at first but the price to performance is not so good. And I dont need the 24/7 low error valudation that come with the workstation cards at this time. Im in the pro-sumer phase if operation.

If AMD cards could support ray tracing, I would get the R9 390…

Where I live the 970 is 2x to 2.25x as much as the 690 or 780Ti. Again, these two cards are under consideration for their CUDA and bandwith memory. The 780Ti has more bandwith and CUDA cores than one of the 690 GPU cores by far, that I know.

I just cannot find a good head to head comparison for these two in workstation apps.

What is alluring about the 690 is the dual GPU that can be used with other apps.

If someone has real working experience with these cards, please chime in.
