Scaling in 4K is decent. Depends on the game though.

It still baffles me people even buy titans.. seeing as superclocked 780 acx from eVGA is the same if not better for 400 less.. lol..

The 780 has 3GB of RAM, the Titan has 6GB of RAM... It all depends on what it's to be used for.

Imagine the PSU needed for volt unlocked 4-way titans.... Some are reporting over 1200W usage for dual titans at 1.3V when benchmarking.

 
This is why some enthusiasts buy 2 PSUs.

What an f'ing joke. They refuse to allow quad sli support for the 780 cause its "a titan thing" so I sell my 4 780s and my monitor to get 4 titans due to some ignorant limitation. Then they release the. 780ti and it supports quad sli. Odd. Care to explain Manuel or whatever your name was? Course not. It's gonna be difficult, but next time around I'm going ati for the first time in my life. If nothing else it will save me some money. Nvidia has gotten far too greedy for its own good.

As Jacob mentioned, Quad SLI support is limited to Titan as our flagship Geforce product.  We do not have plans to add Quad SLI support to other Geforce 700 series GPUs. 

So why does 780ti have it?

This thing has become a bit emotional, i guess.
But there is something that is not right on nvidia´s politics, that makes me think about changing to amd sometimes.
They have a politics of disabling feautures on their cards to force people to spend more money.
It´s not only quad sli on gtx 780, also disabling double precision and most of all disabling physx, if the nvidia driver finds some amd graphics card on your pc.
So you have a nvidia card with physx and you want to use it as a physx card with an amd card for rendering, than the nvidia driver disables physx.
And it is not a technical issue, it has proven to work perfect if you use a hacked driver, until nvidia disables it again with a new driver
and of cause people have allready payed for the physx ability of their card.
It´s only that nvidia wants to force the people to buy nvidia cards only.
I choose nvidia cards 80% of my purchases, but this way of treating customers is not okay.
I´m fully aware that this has nothing to do with Evga, but with nvidia and i don´t want to offense anybody at these friendly and helpfull place.

It seems with gtx 780 you have to do some kind of driver hacking.

Yes u can use it with the very first g110 driver ever made. It doesn't even recognize the card, just calls if a g110 and performance is worse than with a single card. Per first hand experienxe

Exactly. After buying 4 of the 780s I find out my box was apparently a misprint and it didn't support quad sli, which ironically was supported by every card before it.

The reasoning? They didn't really have one, just that the gtx series was no longer the enthusiast level card. They were now the titan line/series and price has doubled.

So like a moron, instead of having a 750 dollar physx card I sold all my 780s, my 1600p monitor, and saved for a month or so to buy titans. I was Bent but just when I get it out of my hair, they drop the 780ti.

Now they enable the cores in the 780ti that are disabled in a card that previously costed hundreds more and was from the "enthusiast" line, and it SUPPORTS quad sli. But what?!? I just heard straight from the horses mouth that feature was now a "titan only feature" and wouldn't be used on 7 series cards. So what changed?

I literally pity people who bought a titan or a 780. Their should be a class action suit brought up. Nvidia needs to be checked. Even if I wasn't a titan owner. (I highly doubt it) but maybe they realized they made a mistake or went a little overboard, fair enough. Then they launch this thing a few months after the 780 and it literally mops the floor.

We were all taken for fools. Of course, if next gen games start using a ton more vram it could be a saving grace. Problem is, 4 titans can't run current games at a reasonable speed at 4k reso as if is. Without the AA that would be required to use all that vram.

I can get past all the vram, the speed, the price, the order and dates and times... What I can't get past is the lack of 780 quad sli support and then saying its titan only so I make a tremendous investment, and then they put it in the 7 series LOL.

Might as well A) give it to the guys with 780s now like u should have from the get to instead of screwing them to try to push people into buying a titan ( cause we know most of your market can afford 4000 in video cards alone anyhow ) and B) forget the "titan" line and view if as the one off card it was supposed to be. Return to the gtx series as being the flagship product.

For those of us who take pride in having the top card and being used to spending 500-600 a card, all of a sudden changing that to 1000-1200 is a shameless money grab and it's sick.

The end

3Gb vram is going backwards will be obsolete. Stick with the Titans  
Here are some facts  from Toms hardware

Battlefield 4 Played in 4K With Four OC GTX TitansBy 20 OCTOBER 2013 21:02 - Source:  
 
 new video has been posted on YouTube, showing some gameplay of the Battlefield 4 Open Beta in a (higher than) 4K resolution. The resolution by which it is played is 4800 x 2560, which is achieved by using three 30" 2560 x 1600 monitors in a portrait Nvidia Surround setup. Do the math -- that's 12.3 megapixels!
 
To bring enough juice to the displays, a total of four EVGA's GTX Titan SC's have been used in conjunction with an i7-3970X clocked to 4.8 GHz, as well as 32 GB of Corsair Dominator Platinum 2133 MHz memory. All of the in-game graphics settings have been maxed out, including the Anti-Aliasing settings. According to the description of the video, a total of 5.1 GB of graphics memory was used.
 
The recording itself wasn't done at the 4800 x 2560 resolution, but rather at the 4K resolution (4096 x 2160). On YouTube, it can be viewed in its 'Original' quality, though beware, you'll need a hefty Internet connection and system to be able to play it, not to mention that you won't be able to see the full beauty of it without a 4K monitor. End
 
My opinion
You couldn't give me 4 780 ti over 2 Titans
 
 
 
 

Was this person using an approved driver? Was this a work around to enable number 4? I mean, the system flat out can't be verified, so until there is a working driver, this means nothing other than someone placed a quick fix.

According to NVidia, there is still no authorization for 4 way SLI, only 3 way, below the 780ti... So yes, we are probably wrong. Go read the SLI feature on NVidia Com. Remember, no one is creative enough to come up with hot fixes. That is why we can't overvolt past 1.212v since it is NVidia locked...

Another guy using 335.23 approved driver. http://www.3dmark.com/3dm11/8648673 August 25 2014.

As stated in the other thread, I am going to follow one. We have three threads open, currently, that are thriving off of the the two 3dmark submissions. NVidia still States that this is not possible, so with all other ways around NVidia stuff, they have probably figured one out for 4 way SLI. That is not surprising at all.
