Optional GPU Upgrade Plan?

[Gooey7]

I'm going to be building a new desktop relatively soon, and ideally I want to begin purchasing parts within the next 2 weeks. The goal of my PC is smooth gaming (60+ fps) at 4k resolution with ultra settings on AAA games.

Presumably, nVidia is going to announce the 1080ti relatively soon. Now, while past predictions of this announcement have been wrong, I don't want purchase sli-1080's or a Titan X and regret not waiting if the 1080ti IS announced within the next month or two. Thing's I am aware of:

• 
  - Technology is always evolving, and playing the "X might be just around the corner" game is very dangerous
  
  - There is no guarantee that the nVidia will announce a 1080ti, despite what articles have been published lately
  
  - There is no guarantee that the projected specs of the 1080ti will be adequate enough to play all AAA games with ultra settings at 4k
  
  - There is currently no consumer grade 4k monitor that goes beyond 60 Hz anway

With all this in mind, my question is this: Are there any manufacturers that offer some sort of upgrade program? i.e. if I buy sli 1080's now, and pay a fee for this program, if the 1080ti is released in a certain amount of time, then I can return my 1080's pay the difference, and get a pair of 1080ti's?

Also, I'm planning on having a custom WC loop. How long does it take water block manufacturers to have new blocks for new GPUs?

Lets be real here.

GTX 980 TI was about 30% faster than the GTX 980.

Now if we saw that same kind of boost than a GTX 1080TI still wouldn't be able to play 4k ultra at 60FPS.

So i mean really, GTX 1080 SLI is still more powerful than anything the GTX1080TI would be.

That said, even GTX 1080 in SLI could have some problems with 4k.

Custom blocks depends on the card. Zotac probably won't ever get any custom blocks. MSI might have them after just a few days.

GTX 1080s with reference designs aren't bad - my EVGA SC is a reference design and could take a reference waterblock no problem.

Thanks for the reply! If I went 1080 SLI, I would go 1080ti SLI as well.

But it's good to know that if there was any "upgrade" option, I'd be stuck waiting for water blocks anyway. Hmmm. Might just go with Titan X SLI then.
