Defiantly the 7970s. The 4gb 680s are kinda a sham unfortunately, and its a shame because I really like NVIDIA so I would love to recommend them but I cant say they are worth the extra money at all. If you do do 680's, don't even bother buying the 4gb version.

OP:

Get (My order of choice)

  1. 2 x Titan (or tri if you have money)
  2. 3 x 7970 (or quad)
  3. 3 x 680 (or quad)

You CAN'T get wrong with the Titans, its just pure power.

Again this is crap coming from you, how do you get the numbers. 5% ?? 300$ ???
600$ eek.gif

are you trying to justify your purchase on this thread?
So you are sure? But you don't know??

Ask Descadent, he has 2 x GTX 670 for 1440p and he has to cut on all Graphics settings, just like 2 x 7970 is NOT ENOUGH in my opinion for 12k pixels.
Its not bugged drivers, its BETA. If people can't make the difference, than its sad for them.

It's called a 690... heard of it? Check my log please Karlitos! rolleyes.gif

Here is a pic showing the three 680 4GB with a nice 690 (2x2GB) for folding purposes while I waited for my waterblocks.



Last I heard the 690 is basically 2x680 2gb on one PCB... correct me If I am wrong /sarcasm

I basically ran two 680 4GB and a 690 on the Sniper.... Ran the game on the 690 Spike Galore and Afterburner showing Max 2GB use... Unplugged the DVI cables plugged them into the 680s (Two at the time) and reran the test.... Low and behold Steady 3GB use with 1GB left.



Difference between a 670 and a 680:



About %5.

Price difference in the 4GB models:

670 4GB @ $469
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130824

680 4GB @ $569
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130794

$100 difference. Three cards => $300 Dollar Difference@~5-8% Performance Difference.

As for "Its not bugged drivers, its BETA. If people can't make the difference, than its sad for them."

If I was still waiting for AMD drivers to mature I will be still waiting for a proper driver for a AMD sponsered game called Far Cry 3. Which they didn't get it to work fine with their hardware and yet gave out copies with their cards. Good Marketing!

I am stating experiance.... Not coming in showing a chart and leaving.

Hence why the title states Tri-Sli and I gave out my feedback on BF3 when going from a 2-Way SLI to 3-Way SLI and I actually made the game work on Ultra when I put in the third card.

I would second Karlitos on the Titans though. If you can afford them Nothing will give you the experiance on 7680x1440.

Thank you.

I almost spunked 2k on the titans... Did the math I would have paid a premium $700 for cards and blocks to replace my rig but said... Wait for next gen!

I still say the 7970s, Remember the 680 4GB can't use all 4Gb because it's bandwidth limited, It was pointed out numerous times, However the 7970 has no problem spreading the bandwidth lovin' around with it's rediculous memory bandwidth it can well and truly make full use of all 3 gigglbytes of Vram


As for everyone else here, Seriously there is nothing wrong with crossfire and eyefinity, AMD drivers are fine, Stop spreading the misinformation not only are these cheaper but they are faster and better suited to the job, The titan while it may be better then the 7970 is twice the price and upwards, the 680 while a fine card is not suited to surround resolutions due to the aforementioned problem and we aren't talking 5760x1080, We are talking big boy's 7K* 1440.

Like it or lump it, This is something the 7970 was designed for.

I really don't know where so many of you guys are getting the idea that the 4GB Kepler cards are 'bad' simply because of the ratio of bus width to memory capacity being relatively lower. I've never seen a reputable reviewer EVER say something like "well, the extra memory on this card is a gimmick because the bus width is only X-bits wide so there's not enough bandwidth to utilize this much memory". I've read 100's (if not 1000's) of GPU reviews over the years, and never seen anyone say that.

What I always see is reviewers saying that "the power of the GPU itself is not enough to be able to utilize (some extra amount of vram)".

I'll give you the most recent example, the [H] review of the 2GB vs 4GB GTX670 in SLI:
Quote:
" That header explains the situation we experienced most. There were some advantages of being able to enable higher MSAA settings at 5760x1200, especially in the case of Hitman. However, while we were technically able to enable these settings, or complete a run-through, the performance wasn't fast enough out of the GeForce GTX 670 GPUs to actually allow that high of a setting to be playable. It's like putting beefy off-road tires on a Yugo, sure the capacity is there to go off-road, but the Yugo lacks the performance to get us over the terrain.

To really show off the advantage of 4GB of RAM on GeForce GTX 670 based video cards, would be to use no less than a three-card 3-way SLI setup. At that point, the performance may be there with GTX 670's to actually utilize the high settings 4GB of RAM would allow.

Another way to show off the advantage of more VRAM, is to simply put it on faster GPUs. In this case, we'd like to see what 4GB of RAM can do with 2-way or 3-way GeForce GTX 680. The GeForce GTX 680 would be more able to give us the performance we need, to show the benefit of 4GB of RAM.

As it stands, the GTX 670 is just a bit underpowered, even in 2-way SLI, to show the benefit of the higher VRAM capacity."

It's very clear by what they're saying here that the issue at hand is the actual GPU performance, not some bad ratio of bandwidth to memory capacity. They also did find one game in their tests (Hitman) wherein there was a distinct advantage to the 4GB cards vs. the 2GB cards in terms of increasing the max playable settings. So it's really not logical to conclude that the bandwidth/capacity ratio is 'the problem', otherwise there'd be NO games where the 4GB cards perform better than their 2GB counterparts.

This all being said, if someone asked me, I'd be inclined to recommend the AMD solutions for such a high resolution, and the reason for that is simply the bandwidth. There is no question that, as you go up in resolution, bandwidth becomes more important (i.e. more likely to be the limiting factor) to your performance, and AMD clearly wins in this regard.

So, assuming that one 'gets lucky' and doesn't have microstutter issues (or any of the other problems) that a few people claim on this thread to have 1st hand experience with, on paper, the AMD solutions should perform better at such an extreme resolution.

However, if it was ME, I'd probably still get the Tri-SLI 4GB 680's, because I'm another person who's been 'unlucky' with AMD multi-GPU solutions in the past, and overall I think that nV provides the more trouble-free double and triple GPU experience (quad-gpu tends to scale really bad so I don't really recommend it for either brand, personally ... no offense, K redface.gif)

... but again, that's just me. And I'm not saying my experience is the only possible one wink.gif

Also, at SUCH a high a resolution as the one we're discussing here, I have to wonder whether 3GB might start to become a limiting factor in some games, and thus if one might actually be better off grabbing the 4GB cards ... something else to make one go headscratch.gif

AMD 7970 3GB from experiance is not a limit factor due to the bandwidth.

Nvidia however is very limited in that respect and the more Vram given the better.

all the reports from the major tech sites scrutinizing frame metering suggests SLI over CFX until AMD comes out with a fix.

1 GPU = AMD unless its Titan
multi-GPU = Nvidia until AMD fixes their frame latency

To add to the 2 vs 4GB Kepler debate

I play all my games maxed out at 6000x1080 and I can't really use MSAA on intensive games with 2GB VRAM and need to default to FXAA...it all depends on your resolution and what levels of AA/mods you might wanna run.

But the conclusion of your article is pretty much my opinion

The Bottom Line
We've given the ASUS GeForce GTX 670 DirectCU II 4GB video cards plenty of opportunities to prove to us why we would need 4GB of VRAM on these. Unfortunately, these have come short of proving this. We tried pushing a single ASUS GTX 670 4GB to the max on a 30" display, at more than playable settings, and also at 1080p. We saw no advantages with a single card. Then we put two together in SLI and tried to push them to the max at 5760x1200. What we found was that higher settings were possible to enable, but the performance wasn't there to allow them to be playable. Simply, the performance of GTX 670 isn't enough to utilize the capacity of 4GB of VRAM.

This is a shame, because the extra RAM has pushed up the pricing on the ASUS GTX 670 4GB to levels that are near Radeon HD 7970 GHz Edition and GeForce GTX 680 video cards at $459.99. Both of those video cards are clearly faster than GeForce GTX 670 GPU based video cards. So the extra money, doesn't buy us the extra performance we would want. Instead, the extra money, is better spent buying the faster GTX 680 or HD 7970 GHz Edition GPU based video card, to get better performance in games.

To make the 4GB of VRAM on the GTX 670 work for you, you are going to need at least three of them for 3-way SLI, to give you the performance to back up the VRAM. Or, we would also like to see 4GB of VRAM on 2-way GTX 680 overclocked, or even 3-way GTX 680. There are advantages to more VRAM, and 4GB can smooth out performance in a lot of games, but today's games are more GPU demanding than ever. These newer games require a lot of performance, and GTX 670 is already starting to show its age in today's latest games. We are already experiencing today the fact that we need faster GPUs in games like Far Cry 3 and Hitman: Absolution.

As it stands, if you want two good GeForce GTX 670 based video cards, stick with the 2GB models, and save some cash. ASUS offers a GeForce GTX 670 2GB DirectCU II TOP video card, which we've evaluated and overclocked very well. If you need more VRAM, look at the GTX 680 models to give you a better experience. ASUS also offers 4GB GTX 680 cards, and we definitely want to evaluate those in SLI.


Yes the 4GB will help, but justifying the much higher price is not worth it.

In my opinion, if you really want full capacity of Vram, the Titan with 384bit and his 6GB is just the BEST FREAKIN card on the market for HIGH resolution thumb.gif
