Even as a computation card, Titan Z just doesn't make sense. A pair of Titan Blacks is cheaper and faster, with the same amount of VRAM per GPU. It's just a bad product.
Like Ryan explained earlier in this thread:
Nvidia doesnt need to market the Titan as a computation card. Those who need CUDA cards are perfectly aware of that Titan Z exist and you mostly dont see them hanging around on public forums like this and therefor you only get one side of the story. Gamers. Which I side with that should have gotten GTX 790.
Here is a link to the actual PCPER web review:

Interesting results!!
What I found interesting in that review was the Titan Z with a single fan makes less notice than a closed loop cooler on the Radeon?

Noise
What I found interesting is there was no temps shown! Makes you wonder doesn't it?
The review didn't make TitanZ look worse than expected. Too me it made the 295x2 look better than anticipated....Figured it would be closer.
in the video I think they pointed out the video was because the 295x2 has two fans and two pumps and it was coming from the single 90mm fan that cools the VRM
Indeed. At current ad prices that would take over a million ad views to make back that kind of money. On top of hosting and paying the staff.From a single niche review? No way.
Buying a single card is only worth it if you it ends up cheaper than buying two cards
Surely a review site as big as Anandtech can afford to pony up $3,000 to buy a card of their own to do benchmarking on it. The ad revenue from the gloating AMD fanboys alone would pay for the purchase.
It's kind of scary that none of the big review sites are willing to do this, as it allows NVidia (or any vendor for that matter) to push a potentially horrible product to the marketplace without any way for a customer to know if it's any good.
Well the most important thing to note is the actual slot width.
First it was rumored 2.5 slots
Then at release it was 3 slots.
PCPER says it's 2.5 slots, which means it actually makes sense (in terms of space) to buy 2 titan z's vs 4 titan black. The 0.5 slot is breathing room, so it effectively fits 2 titan blacks into 3 slots.
If still doesn't make sense. Someone who is buying 4 Titans could put them on a mobo with 4x PCIe lanes. The space argument doesn't work. The noise argument definitely doesn't work since 2x Titan Z is slower than 4 Titan Blacks so you are not comparing apples-to-apples performance. Then there is the fact that you would have almost $2,000 left over for waterblocks to cool the Titan Blacks vs. air cooled Titan Zs.
Worse, one could buy 2 watercooled 295X2s for $3k and have $3k left over for quad-SLI GM210.
The fact that we need 10 pages to try and come up with any reasons why Titan Z makes sense proves the card is a failure for PC gamers. Having said that, it could sell 100,000 units to financial institutions, research centers, natural resource firms, etc. For those firms, if they are running hundreds of clusters of these cards watercooled in limited space for compute work, then this card could easily make sense.
Titan Z should have never been marketed as a gaming card. If NV marketed it as a $3-4K compute card, most of us wouldn't complain about its price. For $3K, the fact that it's slower than 295X2 in games and costs double but has an air cooler is simply inexcusable. Let the professionals spend money in these cards since for them $3k is not a lot.
Well, for any serious compute work, especially in massive scale, I seriously doubt a card without ECC memory and workstation drivers will cut it. It's really sad though, if Nvidia had gave it professional drivers and ECC memory they would sell like no tomorrow.

Oh, and in terms of power: R9 295X2 > 780Ti SLI > Titan Z.. Titan Z is significantly lower than 780ti's SLIed.
Noise: Its quieter than both the Radeon 295X2 and 780ti SLI

R295X2 exhaust its heat out your case as well as taking waste heat from your case out for you, killing two bird, one stone as they say.
