Hmm folding never interested me, but yer if you have enough wealth to buy them, go ahead.
 
2x EVGA GTX 780 Ti FTW Edition 3GB's is what I plan on using for HD Video compiling, MD5 hashing, doing certain renders for friends of mine and the games I like doing.
The GTX 790 would be a nice thing to have around and I would not mind having a pair, but never for 1100 euro's a card ...
As I don't have 1100 euro's for a mass produced VGA card that is Made in China  
 
Now if it were an Engineering Sample, then I see it as a different matter, even though I will always try getting it for a lot less

If they release this Beast,i would like to see the numbers a card like this could put out.
And of course how much it will actually cost.

Nvidia ”GTX 790” Will have 10 GB GDDR5 of Memory, 640Bit Bandwidth and 4992 Cuda Cores – Stated to Release sometime February.

It appears that the ”GTX 790” will not be a Dual 780 Ti, a Dual Titan or even a Dual GTX 780. It is rather something inbetween these three. A 780 has 2304 Cuda Cores, a Ti 2880 and a Titan 2688. The Nvidia Geforce GTX 790 will have:

• Cuda Cores: 2496 (x2)
• Memory: 5Gb GDDR5 (x2)
• Mem Bus: 320 Bit (x2)
• Core: GK110 (x2)

The interesting thing is that Maxwell is geared for release anytime now (maybe by tomorrow) and if this leak is true then it could mean that the Maxwell Flagship isn’t here as of yet. Otherwise it would make less sense to release the ”GTX 790”.  Then again both Green and Red have made seemingly illogical moves in the past.
The other obvious reason, and the one i think is much more likely, could be its response to the Dual GPU Vesuvius that AMD is preparing. A Dual vs Dual, Green Vs Red showdown. However We can see that even with their much better Reference Coolers Nvidia has curtailed its Cuda Cores while on the other hand Vesuvius would be full blown Hawaii XT Cores on their bad reference coolers. Possibly Vesuvius will not come in a reference design at all, but that is mere speculation on my part.
Finally, our source also says that you can expect the Geforce GTX 790 anytime in February. Also there is word in the air that Nvidia is deciding against a GTX 780 Ti 6GB.

True,very true

790 wont make nvidia delay maxwell its already  got preorders for the mobile chips of laptop vendors 
 

Ya, the laptop chips are just rebrands yet again. 

They can always use the new arch with 28nm for dual gpu and call it Maxwell. Better perf/watt. The new arch has better perf/watt. But, a new arch combined with a new node is where you see a real performance jump, sequentially, generation over generation.
One of the reasons for Nvidia to stay on 28nm is if they know that AMD will not be releasing a 20nm new arch gpu this year.

One is that 780 never gonna see 6GB Vram unless the card is named titan.

Ehem...

It bears repeating that nVidia doesn't do anything unless AMD either might have a threat to a current lineup or can't do anything about it.  

1. All dual-GPU nVidia cards in the past have doubled up the number of cores and Vram of the reference models only. There is no business incentive to go further since the competition isn't doing that either.  R9-295x2 has 8GB total due to each Hawaii GPU having 4GB for itself; AMD isn't putting 16GB on the card.  
2. To keep from cannibalizing Titan-Z, a "GTX790" could simply have it DP disabled and have half the Vram due to GTX780 and GTX780 Ti's popularity despite 3GB per GPU.
3. Of course the only reason I can fathom a "GTX790" to come is due to R9-295x2.  It is already projected to be 37% faster than Titan-Z by single-precision calculation alone (11 TFLOPS versus 8 TFLOPS)-- AMD could price R9-295x2 at $4000 and still win per dollar.  But according to an unsubstantiated rumor from nordichardware, a Swedish retailer accidentally listed the ASUS R9-295x2 at 18,000 Crowns = 900 Dollars.  So the price may start out way lower than Titan-Z; but nVidia could also debut Titan Z cheaper too; I don't think $2999 is in stone.

It wont happen NVidia will not want to dip into their  higher end market that is the Titian. If amd does not offer something of almost equal to better performance it defiantly wont happen.

There are several tiers of Titan now; the point of competition is steal away customers, and the best way to to that is to fill the gaps in a competitor's portfolio-- nVidia is asking for it given the gap between Titan Black and Titan Z.  
 
 
If R9-295x2 manages close enough performance for way less price, that is enough to threaten Z's sales and cause nVidia to react.  We just don't know what they will react with.  I'm sure some would like Titan-Z to drop in price, but I think making a GTX790 out of a pair GTX780's with 3GB each is far more likely; and will consume way less power than whatever Titan-Z is expected to use.
