so i have a gtx970 and im a little confused about directx 12, i've been thinking about getting myself an 980 ti or waiting for pascal, the thing is, will i be able to use a gtx 980 ti and the 970 connected at the same time whit directx 12? is it really worth it buying a 980ti if i already have a 970?

Multi-GPU with DX12 is still a work in progress, which is two of the same gpu. What you're talking about is Multi-Adapter which is still a whole other can of worms, using two different gpus. I would not invest money and hope it is coming down the pipeline or that it even works. If it works or not is up to the developer, whether they code for it or not. The path is there in DX12, but the game has to be written for it. And given how hard it is to just do multi-gpu, I wouldn't hold my breath for multi-adapter.

I've tried my best to understand, but I'm still unsure as to what DX12 actually is and what it does 
Whats the big fuss all about?

It allows game/software developers direct access to HW. It's like having the instructions to build a lego kit, instead of mucking about building the a lego kit by picture. THis is obviously a very simplified explanation.
In some ways its the opposite. In earlier versions of DX you could for instance load a texture with little more than calling a create texture function specifying a filename - and then the API and drivers would go away and do everything behind the scenes you had little control over where it went on the GPU and what was in the memory locations on the GPU - with DX12 you have far more access to what data is actually residing on the GPU and can potentially do all kinds of invalid things to it.

remember that dx12 multi gpu sounds great but the program/games need to write code to use this feature.
And currently half of games and programs dont even use sli/crossfire and they been out for years so just get another 970 to run in sli

i dont really want that much of a performance boost right now, its just that im wondering if its worth it for 400€ to change from a 970 to a 980 ti, if its that much of a change, or maybe do you guys have any speculation about the price range of pascal, its quite near so if it isnt that much of a boost from 970 to 980ti maybe i should just wait a little more, what do you guys think? im not a fan of sli because like it was said above the games have to be written for it, and not many of them are actually doing it, i just wanted to know about directx 12 just to use the 970 along whit the new one instead of keeping it in a box.
Just wait it out if the performance boost isn't important, likelihood is Nv will drop Maxwell optimisation anyway and performance will drop with Pascal optimisation taking precedence anyway much like they did with Kepler.
