So I made a thread earlier this year about getting a GTX 680 or GTX 670, but kind of been contemplating the 680 or 7970 since waiting for a bit. I thought about the GTX Titan, but can't convince myself to spend $1,000 on a single GPU. I would much rather get 2 cards and get better performance.
I'm looking at this GTX 680 because I heard/read that it is one of the better cards that runs cooler and better performance
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121705
I thought about getting the 690, but I'm kinda on the fence with it.
For AMD, I don't know much about the brands on that side. I have heard that this one is pretty good
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125439
Has the ASUS ROG 7970 GHz performed well? Because that is the one that I would like to get if I got AMD
http://www.amazon.com/DirectCU-1000MHz-Overclocked-Graphics-HD7970-DC2T-3GD5/dp/B00739TCH8/ref=sr_1_1?ie=UTF8&qid=1362627304&sr=8-1&keywords=asus+7970+ghz
Now I know there isn't much difference with high end cards, but I really just would like some opinions. I know some games have Nvidia favored setting like PhysX and some others. All I've ever had is Nvidia, so I don't really know if the difference with PhysX on and off is noticeable if I had AMD. Any suggestions are welcome.

The 7970 GHz is a stronger card and scales better in crossfire. Get that!

The GTX 680 is going to be much more efficient in SLI, which generally means less power, cooler and quieter, while giving you better performance. Not to mention you won't have to worry about "if the difference with PhysX on and off is noticeable", which it is. It's also common knowledge that AMD has a ways to go in providing Crossfire driver support that is anywhere near as good as Nvidia SLI driver support.

AMD's HD 7970 GHz Edition CrossFire setup has its moments, but flunks far too many tests due to poor multi-GPU driver optimizations by AMD."

Having used two SLI setups and two CF setups, I find far less hassle with SLI. (5870's, 470's, 6950's and 680's). It also appears, at least without v-sync, CF has issues with runt frames, which basically means a lot of frames pretty much don't get shown due to not spacing out the frames. With new testing methods coming to fruition, you can expect AMD to address these issues, but until then, SLI is performing better.

For the most part, they scale about the same, and the 7970 Ghz edition does get slightly higher FPS, but if it has more hitching and runt frames, it does not look as smooth, which ultimately is the goal.
That said, if I were to buy today, I'd get 670's (I got my 680's last year before there was a 670, and 7970's were really expensive).

Honestly all brands are good. But if you want the best, get a Vapor-x. There overclocking software is great, and the custom unlock their PCB's so you can always overclock as high as it will go! I have seen some with 1400 core and 1875 memory!

I have looked into the 670 4Gb editions. Isn't the 670 supposed to be almost as fast as the 680?

7970 GHz > 680=7970 > 7950=670.
Also NO CARD is colder than the Vapor-x, that is the point of it. You really should overclock. It is as easy as pressing a button.

They also do a good job at metering the frames in SLI. As some have mentioned, they use FPS limiters in order to get crossfire to work well, without stutter. If you have to reduce the frame rate in order for a good experience, their FPS advantage is lost, and probably at a disadvantage.

If its all about performance, I'd go with 680's even now.

Is EVGA still the go-to for nvidia? I know they are pretty reliable, I've had my 470 since it came out, and its been fine. I've read Asus does pretty well, along with the Gigabyte cards. Like I said in my first post, I'd really like to go with the "coolest card" because i'm tired of having to run my fan so high. lol

Odd considering the 7970 GHz is clearly stronger, but you are right that they weren't always overpriced.

That

That isn't true. One of the biggeat benifits of crossfire is the increase in minimum framerate. For instance my 7970 GHz is overall around 10-20% stronger than my old 6950 cf, but my minimum framerates in metro 2033 went down from a (high for that game) 40 FPS to about 25 fps. Also in borderlands 2 I used one 6950 with vsync but it sometimes dropped to 40 fps in intense fights. When I enabled crossfire that didn't happen anymore. Sorry but crossfire was great in my experience even though I had one in a x1 slot!

Minimum FPS wasn't even what I was talking about anyways. Microstutter, hitching, jitterying, that is what I was talking about. Many people use FPS limiters to fix it on Crossfire setups, even if YOU don't.
Just because you don't seem to be bothered about microstutter, doesn't mean others aren't. Even BigMack70 uses a FPS limiter to avoid stuttering. Look at the article on the crossfire issue, the comments are full of "Just use a FPS limiter".
If you aren't notice it, it may be due to v-sync or you don't care. The tests are without v-sync, though v-sync is a limiter too. How they compare with v-sync is in question as well. Luckly, the full article, when it is done, is suppose to include v-sync numbers, good or bad (7970's may do good in v-sync, we just don't know yet).
Either way, the end result matters more than FPS unless you benchmark.

I would recommend 670's in SLI.
1. They are cheaper.
2. The difference between 670 SLI and 680 SLI in most games is 4 fps.
Lol , who wants to spend an extra 50-70 dollars for that 4ps diffference.
At the moment, Gtx 670 SLI's are the way to go, especially on resolutions of 1920x 1080p
However, if you planning on gaming on 2560p or triple monitor setup , then you should crossfire a couple of 7970's : )

Maybe you don't know, but I and anyone who bothers to check does know. AMD has fixed the lattency and stuttering problems. Look up crysis 3's lattency tests abd you will see AMD beating Nvidia half the time. WAKE UP! Your 680's are great, but there are not infallible.

They helped with latency issues in a few games, but that is another issue all together, which affected single and multi-GPU setups. This is a crossfire only issue, that has nothing to do with latency, and everything to do with frame metering.

Surprise!, it has nothing to do with frame metering in crossfire. Nothing at all. Surprise! that was just a sample with the first 3 games they looked at for fixing the frame latency issue. Those are 2 different issues, if you are not aware and the latency issue has just begun to be fixed. It is not solved either, though I'm not sure how close they are, as its been over a month since the first 3 games were dealt with.
Here, this is from the same site, written AFTER the review you gave:
http://techreport.com/blog/24415/a
Quote:
Interestingly, in this page of Ryan's Titan review, he reproduces images that suggest a potentially serious problem with AMD's CrossFire multi-GPU scheme. Presumably due to sync issues between the two GPUs, only tiny slices of some frames, a few pixels tall, are displayed on screen. The value of ever having rendered these frames that aren't really shown to the user is extremely questionable, yet they show up in benchmark results, inflating FPS averages and the like.That's, you know, not good.
As Ryan points out, problems of this sort won't necessarily show up in Fraps frame time data, since Fraps writes its timestamp much earlier in the rendering pipeline. We've been cautious about multi-GPU testing with Fraps for this very same reason. The question left lingering out there by Ryan's revelation is the extent of the frame delivery problems with CrossFire. Further investigation is needed.
Again, look at the date. "February 26, 2013" A whole month AFTER you claim it was fixed.
That is not to say that AMD won't start work on fixing this issue, but it is currently unaddressed.

First of all, the 13.2 Beta7 has been released 26.02/2013. how come the article was written 16/01?
Frame Metering? It was all about Microstutter, Frame Latency & Rate.
One of the tougher questions we had for AMD, in the wake of our discovery of these latency issues and their subsequent move to fix them, was simply this: how can we know that we won't see similar problems in the future? Dodd addressed this question directly in our correspondence, noting that AMD will be changing its testing procedures in the future in order to catch frame latency problems and prevent them:
Up until this point we had mostly assumed that there were occasional flickers in frame rate, but we had thought these were related to the fact that modern games mostly have streaming architectures and limitations of scheduling in the OS. We definitely will start regular measurements to ensure we track improvements, and stop regressions. Long term, we want to work with game developers and Microsoft to ensure these kinds of latency issues don't keep cropping up.
That's exactly the sort of answer we want to hear, and we'll be watching and testing future Radeon drivers and GPUs in order to see how well AMD executes on that plan.
That's with the latest 13.2 Beta7
They Keyword is just a "Driver Update".

Sorry to break it to you, but these are 2 separate issues. You'll have to read the article to understand. The latency issue was affecting single cards, but this one only affects crossfire. It isn't a problem with frames being slow to be rendered, it is a problem with the two cards in AFR not coordinating their output. The tradition FRAPS method of measuring does not work, which is why every latency test with crossfire in the last month has commented on their multi GPU frame latency tests are inaccurate.
Stick your head in the sand if you like, but that will not solve the issue. Had TechReport not brought the frame latency issue to AMD's attention, that would still be a problem. Now that Pcper has brought this up, AMD could actually work on it. I'm sure you'd rather live in ignorance, right?

Sorry to break it to you, but these are 2 separate issues. You'll have to read the article to understand. The latency issue was affecting single cards, but this one only affects crossfire. It isn't a problem with frames being slow to be rendered, it is a problem with the two cards in AFR not coordinating their output. The tradition FRAPS method of measuring does not work, which is why every latency test with crossfire in the last month has commented on their multi GPU frame latency tests are inaccurate.Stick your head in the sand if you like, but that will not solve the issue. Had TechReport not brought the frame latency issue to AMD's attention, that would still be a problem. Now that Pcper has brought this up, AMD could actually work on it. I'm sure you'd rather live in ignorance, right?
Yeah I'd rather to.

Minimum FPS wasn't even what I was talking about anyways. Microstutter, hitching, jitterying, that is what I was talking about. Many people use FPS limiters to fix it on Crossfire setups, even if YOU don't.Just because you don't seem to be bothered about microstutter, doesn't mean others aren't. Even BigMack70 uses a FPS limiter to avoid stuttering. Look at the article on the crossfire issue, the comments are full of "Just use a FPS limiter".
If you aren't notice it, it may be due to v-sync or you don't care. The tests are without v-sync, though v-sync is a limiter too. How they compare with v-sync is in question as well. Luckly, the full article, when it is done, is suppose to include v-sync numbers, good or bad (7970's may do good in v-sync, we just don't know yet).
Either way, the end result matters more than FPS unless you benchmark.
Even SLI suffers from stuttering this is only a big deal because AMD has the balls and admitted it! Crysis 3 has major stutters and performance dips on my SLI setup. I see stutter on BF3 as well, currently Tomb Raider has the problem as well

It is true, there is some stutter in some games, but not like the crossfire issue, which is pretty bad, unless you use a limiter or v-sync.
You are comparing a new release bug, with a wide spread issue.
Feel free to read about the crossfire issue, but keep in mind, this particular article is talking about when not using v-sync. You should read the links in it. It also talks about more than the crossfire issue, and just general information about all the causes of stutters for all platforms.
http://techreport.com/blog/24415/a
I personally was running 6950's prior. With v-sync, I was did not see a lot of problems, though I always saw a bit of stuttering here and there. I was not aware that it was considered microstutter.

Look, you can believe the reviews or not. New testing methods are coming as the article I linked showed. You can believe it or not, but since both TechReport and THG has started putting a disclaimer on all their crossfire benchmarks recently, I tend to believe it. Hardocp has always mentioned an issue with crossfire in many of their reviews as well.
If you don't believe it, fine, but remember that the person you are recommending this setup may not use a fps limiter or v-sync, and will have to live with it.

So before we get TOO off track. If I went Nvidia, Is EVGA still the way to go? I have read that the 680 can get up to the same temps as my 470, which isn't exactly what I want. I have heard the ASUS DCUII TOP edition is pretty stellar and runs cool. I always have trouble differentiating the reviews on temps.

680s if you must use Multi Gpu. However the Titan for almost the same dollars has ultra low latency, NO runt frames, and is silky smooth. Titan is 3 to 4x faster than the FASTEST Crossfire in frame delivery times. http://www.hardwarecanucks.com/forum/hardware-canucks-r...
I wouldn't touch Crossfire until it fixes these problems.

Almost all EVGA cards I have come across from friends broke within a couple years. Yes they have good customer support, but why do we all know this? THEY BREAK!
For AMD I know SAPPHIRE builds their cards like tanks, but I have no clue who else to trust on NV. I would guess MSI and ASUS are good choices...

Quiet and cool... also consider the MSI GTX 680 Lightnings.
Both of my cards have a high ASIC (87%/83%) so that's good and is indicatve that Asus uses higher binned chips for their top tier cards.
