The first thing that has to happen is for DX12 to even get released.  MS is working on that with Win10 at the moment.  The next thing is for developers to begin using it in new game development.
 
It will probably be awhile before we see anything actually using DX12.  Possibly later this year.  We'll have to wait and see.

It will be a Windows 10 exclusive as well, so you can't be on Windows 7 or 8.

That is false according to this  >>  http://channel9.msdn.com/Events/Build/2014/9-004
 

So, speculation may turn out to be speculations and not fact.... lol. We'll see at a later date as to what dx12 will support over all. At this point, it's just speculation and hoping for things to work out.

Right now only Windows 10 has the DirectX 12 API and unless Microsoft changes its mind then that might be the only MS operating system to which DirectX 12 is ported.

When DX12 show up you will have 20fps in new games on GTX780.
I don't even think about series 700 and DX12 compatibility.

well it was coordinated  like the new cpus and ddr4s and mobos and video card releases. and benchmark updates. for max intake. and insured consumedge
by having the 700s doesnt mean i dont want it. 20 frames is a guess I never take word or trust me I know . I like to see for my self works for me. I find that official data is never pernament out come.

Did the ops ? get answered? I read the article and listened to the video, and most of the above comments seemed aimed at the OS as opposed to GPU support. So ill ask,will direct x12,be it on win 7-8.1-10-whatever , have support for 7xx series GPUs?

The only thing I've ever seen so far regarding hardware (GPU) support is that everything from 400 series on up will support it.  Might still be a "wait & see" thing yet at this point...

You do not get DX12 until windows 10 is released, and even other past generation cards get DX12 features when it happens.

My only intrest in DX12 is that I heard it will allow GPUs in sli to utilize all the VRAM, 2 780tis will have 6 gbs of available mem, can anyone confirm if this is so?

There is a difference between partial and full DX 12 support. I hope more info will be forthcoming in the months to come.

Do u know if the feature allowing the use of all VRAM in sli would be considered "partial" or "full" DX12 support?

To answer you, yes it will just fine....
I have a 750Ti ACX, and am currently running win 10, with dx12. It works fine, haven't tested any dx12 games yet but Grid Autosport runs awesome on ultra.... Notice I'm on a driver that isn't even out yet 349.90....

its out now what?
 

I'm not sure what he's going on about. 349.90 was released on Windows update for Windows 10 on the 19th of March. I guess you wait for something besides a Benchmark that uses DX 12.

I get irritated at a few things . but latest is 349.90 with no triple SLI support , Runs the supposed DX12 in 3dmark under features. says it will only run on win 10 but I see this in return .look at the version and the corner right. miss info but is it. .whatever. I didn't even ever have 8.1 0n this drive. 
Wound not post the picture but you get it right.?

The trick, to get the latest, is join the fast ring. I'm already on the next build, that enables Spartan, got it over a week ago...

Hotrod u have a 750ti my concern was will the direct x12 combine the vram on the 7xx series cards in sli?

I stand corrected, I guess it will....

Just tested two 3GB 780ti cards in SLI under Win10 10049 with driver 349.90 and DX12 shows 6144MB of dedicated VRAM. So yes, DX12 will stack the VRAM on 700-series cards.

Nice!
