I understand that 590's are more powerful than the 580's, but that doesnt mean they scale as well.
Comparing two gpus with four is pointless. The 590s scale really well in the games I play so that's all that matters. And two 590s will destroy two 580s every time.

That's interesting.. I've never used a 120hz screen as all three of my monitors (Dell U3011) are 60hz refresh rate.. I get 110+fps in bc2 and can't tell a noticeable difference between that and around 60fps; of course, that's because the monitor is capped at 60hz.

That is completely false.

The human eye doesn't see in fps. It sees in motion.
FPS is just a term and a calculation as to the fluidity of something you see on a monitor, or on the big screen at the cinema.
This is NOT how the human eye can see.

24 FPS is what the eye stats to see as fluid, and is the reason why most movies and the old VCRs where in that speed.
60 FPS is very fluid to the eye, and feels very fast and easy for the eye to follow. And is the reason why today its the standard.

The more FPS you have, you start reach the point where the eye speed of transferring the images to the eye starts to be neglectful as to how you perceive it as "more fluid".
Mainly, the human eye will "scale" at around the 85hz (or 85 fps), and above that, its really where the difference between people starts to take place. One person is "agile" enough to see it more, others will not.

At some point of FPS, the human eye will start giving you headaches as the eye starts to "degrade" in how it brings the images to the brain. Some say its above the 200, to others it can be around the 100. Really depends on the person.

first yes, for Nvidia surround at 2560, the quad sli would make more sense. But that isn't the case for the OP, now is it?
Also the games OP plays doesn't necessarily equate to you playing those same games.

And to the OP:

I didn't read the whole thread, but here are my thoughts.

To have any use of 120fps, you need a 120hz monitor. If you don't plan to use one, all this thread is useless.

A couple of 580 will not guarantee 120fps in every game, in every situation. Once you crank up AA, it will starts to get lower.

2x590s is a complete waste for a single monitor. And even that will not guarantee 120fps in every game, as some games just don't scale as good with 4 GPUs, and some even will go less.

If you have to have a very silent computer, pretty much the only option is a couple of 580.
69x0 series are very loud, and 2x590 will also be pretty loud as they will make quite a lot of heat, and you will have to keep the fans a bit higher.

If you get a couple of 580 and a 120hz monitor, you might not get 120fps in every situation, but it will be close enough for the games to be very fluid and be good enough for your needs.

Don't worry I have my AW2310 sitting right next to me, waiting to be put into use. I would think that what I'm looking for is different than what many are, so I personally wouldn't think of it as a waste, I want 120fps in current & future games.

I've also read through reviews that the 590 outputs extremely similar noise & heat levels to that of the 580, the 580 Lightning is actually louder at load, or so I've read.

Though you are correct, the scaling issue of Quad-SLI is what caused my concern, having me think that a couple of OC'd 580's can provide similar performance to the poor scaling of Quad-SLI 590's. I'm also unsure how Quad-SLI would affect older games that I plan to return to, such as Morrowind and the Kotor series.

..Then there is the micro stutter that I've been worried of

Old games will not benefit at all from quad.
That I can confirm.

For single monitor, you can run them with a single 580 without any problems and a much higher FPS than 120.

And newer games proof, well, you can never know.
If you plan on several years forward, maybe, a quad will be ok. And even that, I wouldn't count on it.
I mean, the 295 came out just a couple of years ago, and its already fully out-dated.

Defoler is technically correct, however, he did forget that you can run 3-Way SLI and dedicated a 4th GPU to GTX 580 level Physx IF you are having scaling issues.

I want to mention that while Levesque is correct the 6990 + 6970 setup is definitely a strong setup, it does beat the GTX 580 SLI simply because its 3 GPUs vs. 2 GPUs in your case. Levesque probably didn't see the higher budget, or he would have recommended 6990x2 which is even faster.

I personally just came from GTX 580 SLI, capable of 965 MHz clocked on both, its definitely a game winner for most people. IT WILL NOT GET YOU 120 FPS+ IN ALL GAMES. PERIOD.

I have the ACER GD235Hz (1920x1080@120Hz) monitor. Playing above 120 fps on a single monitor is soooooooooooo nice its all I care for. I am not used to my multi-monitor setup. I added 2 nice and cheap 1080 LED LCDs to my ACER as more of a gimmick and production value than my gaming needs. I am not used to it, and I am not a huge fan of bezel splitting. SO I primarily play on my pride and joy: the Acer.

The GTX 590 is not an easy overclocker on water. Its even harder on AIR, that being said, its quiet, its fast, and works well right out the box.

When comparing it to the GTX 580 SLI setup, rather than thinking of it terms of QUAD SLI vs. SLI or TRI-SLI, I look at it as a slower Quad Core vs. a faster Dual Core/Tri-Core. Something like a 2.6 GHz Core2Quad vs. a 3.2 GHz Core2Duo.

Hitting 30% OC was a huge gain in performance, I hit 822 MHz stable in Heaven, and it performed admirably. Thanks to Alatar you have already seen it. That was from the official benchmark thread for Heaven on OCN. I am 3rd place. Behind the likes of only Faster and CallSignVega who are using true overclocked GTX 580 quad SLI. I don't even hope to achieve that.

Downside, numerous titles and applications currently have a invisible performance throttling due to what we believe is either power draw or overclock protection. IF YOU are not overclocking, this is truely the only probably permanent downside to these cards that you won't have to deal with.

The scaling needs work, but this is true of every dual-GPU card ever released. AMD or nVidia, we all have issues from time to time. Sometimes QUAD-SLI scaling isn't there, but it does require a hefty power supply, a solid motherboard, and a CPU than can unleash them. Any one weakness in the chain, and the entire system is held back gaming wise. The microstutter is marginal at best and various from none at all to obviously needs driver tweaking. Although 120Hz monitors (notorious for the fluid motion) is obviously more sensitive to microstutter, I find it very manageable on 270.61 drivers so far. I am only running 267.85 to overclock.

Getting a GTX 590 either single or double is really joining a small community around the world. And will be a unique experience that very few people will be apart of. That specifically is very enticing to me. Some people can't afford it, some people don't want it, and some people think its crap for X Y Z reason. Which is perfectly okay to me. I don't like doing what every body else does, but I did my research and I took a little bit of gamble due to the VRM scare, but it paid off. 100% satisfied so far, just wish I could turn off the performance throttling in various 3D Mark benchmarks.

I personally would go with the GTX 590 SLI, however, you will be pleasantly satisfied with GTX 580 SLI, however its not future proof for a 120 HZ monitor.
