I've been looking around.
770 sli is quite expensive and is basically the same as 680 sli but with 4gb vram.
This means a boost of only 30% above my until recently 580 sli.
Also looking at EVGA 780SC 6GB as an option.
Finally it is still possible to buy a replacement 580 new.
with no sidepanel fan my case is a bit cramped with it's small size and perhaps not ideal for SLI to begin with.
Last option is to do nothing staying on a single 580.
Have I missed anything obvious?
At this Point I would think that Titan Black SLI offers the best performance and thus being a good performance reference point.

Briefly it appears SLI scaling is 50-60% with some brilliant exceptions

Thanks to everybody using my assembler it warms my heart.
To have a critical piece of code that everyone can enjoy!
What more can you ask for?
You may get a 580 used, but when I sold mine about 18 months ago there were hardly any about on ebay, and none available retail. I think I managed to sell it for about £130 as it was the 3gb version.
I upgraded to SLI 670's which are each about 10% faster than the 580 and about 10% behind the 680 but a good £100 cheaper at the time. I did also have to upgrade my case to fit a 2nd card. Ended up getting a Coolermaster HAF cube where the motherboard sits horizontally across the middle of the case above the PSU and hard drives.
There aren't many reasons why I would ever want to go back to a single card as there was a massive performance increase from 1x 580 to SLI 670. The Kepler cards are also a lot nicer on the power consumption, my PSU is actually not strong enough to support SLI 580's but it works nicely with the 6 series.
You could possibly get a bigger card and pair it with your 580 and hope that SLI still behaves, and eventually replace your remaining 580. Its not recommended, but has anyone else here ever tried it and did it still work?

In terms of generations, the Keplers bring a few advantages like TXAA and Adaptive Vsync, which are certainly not essential, but can be nice to have.
And as Foulplay said, the power consumption is nicer than Fermi. However, I'd add that the more recent Keplers seem even nicer. Before my Titans, I had an 680, and I've been amazed at how nice and quiet the Titans are........ok, once I overclocked them both, modded their vbios to remove throttling, and sandwiched a PhysX card in between them, they're not that quiet anymore. But at stock, they're almost whisper quiet. I suspect that this is the case with some of the other 7xx series too.
I think if I was in your position, I'd wait until Maxwell to either get Maxwell cards, or to enjoy the price reduction of 7xx cards. I probably wouldn't buy another 580 unless I found one really dirt cheap, since that's just throwing money at a relatively short-lived solution.

By chance, I just had this exact same experience, SLI 580, with one that died. In my case, I was very lucky that it was under warranty, and EVGA replaced the card just today. Very impressive customer support, the card was 3 years old.
But, it wasn't clear if they were going to return a 580, or a 760, as being 'equal or better'. 760 is a better card of course, but would break the SLI and thus be inferior overall.
So, since I was expecting a broken SLI, I did a bunch of research.
Short story: I'd recommend buying a replacement 580 for now. It's $100 on eBay, it gets you back to SLI 580 which is still better than any single card solution, and it's cheap. Later, with Maxwell, you can sell these cards and take advantage of Maxwell or cheaper 7xx prices.
Long story, for next upgrade, you'll need to decide how much you can afford to spend. Performance nowadays goes up roughly comparable to actual value of cards. For example, a single GTX 760 2G is a little bit better than a single 580. Not even close to better than SLI 580 though. 760 2G costs $250 now. So, if you went with this lesser card, but did SLI to make it hum, you'd be out $500.
Any single card solution is OK, but not much of an upgrade for the cost. GTX 780 3G, also $500. Can't hold a candle to SLI 760 2G, slightly better than SLI 580 1.5G, but not enough better. Maybe if you sold the 580 for $100, so it only cost $400. And planned on SLI in the future with another $500.
Single 770 is just about even with a SLI 580. Again, hardly can be considered an upgrade, if it costs $350, but maybe it's worth it if you sell the 580, and look toward getting another 770 later.
780ti: total waste of money. If money is tight, you never buy the best card because they get their 'best of breed' surcharge. $750. Not even close to worth it, considering I can get SLI 780 for $1000 which would smoke any single card. Or even SLI 770 at $700 that would smoke a single 780ti.
One good link for SLI review:
[url]http://www.guru3d.com/articles_pages/geforce_gtx_760_sli_review,1.html[/url]
Also, if you are buying as an upgrade now, and not as a stopgap, I think you would be best served with dramatically larger VRAM. Even the 3G 780 cards are no longer viable in my opinion (Watch Dogs is probably only the first), and I would only buy the new 6G version now. 2G cards like the 770 or 760 are right out, I would only buy a 4G there.
So in order of cost, which I think is a pretty good metric nowadays. This does not take into account the possibility of selling your working 580, but it does pay the extra $50 for better VRAM.
$100: replacement 580, since you already have one working.
$300: Single 760. Not really viable, slower than SLI 580.
$400: Single 770. Directly comparable to SLI 580, not really an upgrade, but maybe looking at SLI later.
$550: Single 780. Workable. Not as good a bump as preferred, but pretty good.
$600: SLI 760. Nice actual upgrade. Roughly comparable to a Titan.
$800: SLI 770. Very nice upgrade. Better than a 690.
$1100: SLI 780. About as good as it gets and still be considering 'value'.
Since you are doing Surround now, the SLI 580 may no longer be good enough, in which case you'll have to consider if you'd prefer to upgrade now. Anyway, hope that helps.

Not really... if you are using 3D Surround or 4K (probably). If you are stuck on a 1080p /1440p 3D Monitor 780Ti SLI is a waste of money and power/resources.
But if you are a surround gamer (like me) that awesome 60fps in 3D Surround is pure awesome;)) Depends what you really want.

Right-o, good point. If even the best hardware in the world is still too slow, it's still probably the way to go. But I will still say that if you are on a budget, it's not a good call to SLI 780ti, instead of turning down some settings. The performance delta from 780 to 780ti doesn't seem to justify the extra $400.
And, at the moment, it's a total non-starter in my opinion, because there is no 6G version of 780ti.

One of my life mantras is "time is more valuable than money". Before I bought my Titans, I had never allowed myself to have a top-end PC setup. But I would spend hours in most AAA games tweaking settings and optimising .ini files to try and get the best visuals/performance. Sure, that stuff can be fun sometimes, but it can also be frustrating.
Now that I've got the Titans, I just set everything to max (except maybe SSAA) and enjoy the games. I figure I've probably saved dozens of hours of tweaking by now, and lots of frustration. On paper, my Titans are about the worst bang-for-buck you can get. Yet I couldn't be happier about the $3000 I spent.
Of course, it all depends on your commitment to the hobby and your finances. I count myself lucky that I have a hobby where a guy with a below-average salary like me can comfortably afford the best. If I was into motorbikes or sailing, things would be different.

Have you tried the oven trick to get the card working again? I had a 8800 GTX die on me, stripped it down and baked it... bingo! It came back to life. Still working now in a friends PC 3yrs later, did it with my friends too, and a ps3

Another set of data I forgot I'd researched, is the Anandtech bench.
Here's a comparison in several games, and several resolutions comparing a GTX 590 to a single 770. I'm using the 590 as a proxy for SLI 580.
In general, the 590 is about the same as a single 770. It's faster in some games, slower in others. You can also make other comparisons there to different options.

Aye, the thing about the 590 is that is dual GPU...and relies heavily on SLI to work properly (as you can see from the graph). It also features less Cuda cores than a 770 (I think)

Yes, pretty interesting, even given hardware differences like Cuda cores.
SLI 580 vs. 770:
Seriously behind in Company of Heroes 2.
Moderately ahead in Crysis Warhead.
No real difference in MetroLL, Crysis3, Bioshock Infinite.
I still stand by that earlier comment that it's not an upgrade, more of a straight trade.
For VRAM usage, there are 3 games now that can use more than 3G:

Now though, same idea of "time is more valuable than money", different take. Since I do contract work, any time I spend working is time I don't get to spend playing. So, if I spend $3K for a TitanZ, I need to do a contract to pay for that. If I don't spend anything and keep my SLI 580, I don't have to do a contract. I prefer my free time now.

770 sli is quite expensive and is basically the same as 680 sli but with 4gb vram.
This means a boost of only 30% above my until recently 580 sli.
Also looking at EVGA 780SC 6GB as an option.
Finally it is still possible to buy a replacement 580 new.
with no sidepanel fan my case is a bit cramped with it's small size and perhaps not ideal for SLI to begin with.
Last option is to do nothing staying on a single 580.
Have I missed anything obvious?
At this Point I would think that Titan Black SLI offers the best performance and thus being a good performance reference point.

I upgraded to SLI 670's which are each about 10% faster than the 580 and about 10% behind the 680 but a good £100 cheaper at the time. I did also have to upgrade my case to fit a 2nd card. Ended up getting a Coolermaster HAF cube where the motherboard sits horizontally across the middle of the case above the PSU and hard drives.
There aren't many reasons why I would ever want to go back to a single card as there was a massive performance increase from 1x 580 to SLI 670. The Kepler cards are also a lot nicer on the power consumption, my PSU is actually not strong enough to support SLI 580's but it works nicely with the 6 series.
You could possibly get a bigger card and pair it with your 580 and hope that SLI still behaves, and eventually replace your remaining 580. Its not recommended, but has anyone else here ever tried it and did it still work?

And as Foulplay said, the power consumption is nicer than Fermi. However, I'd add that the more recent Keplers seem even nicer. Before my Titans, I had an 680, and I've been amazed at how nice and quiet the Titans are........ok, once I overclocked them both, modded their vbios to remove throttling, and sandwiched a PhysX card in between them, they're not that quiet anymore. But at stock, they're almost whisper quiet. I suspect that this is the case with some of the other 7xx series too.
I think if I was in your position, I'd wait until Maxwell to either get Maxwell cards, or to enjoy the price reduction of 7xx cards. I probably wouldn't buy another 580 unless I found one really dirt cheap, since that's just throwing money at a relatively short-lived solution.
But, it wasn't clear if they were going to return a 580, or a 760, as being 'equal or better'. 760 is a better card of course, but would break the SLI and thus be inferior overall.
So, since I was expecting a broken SLI, I did a bunch of research.
Short story: I'd recommend buying a replacement 580 for now. It's $100 on eBay, it gets you back to SLI 580 which is still better than any single card solution, and it's cheap. Later, with Maxwell, you can sell these cards and take advantage of Maxwell or cheaper 7xx prices.
Long story, for next upgrade, you'll need to decide how much you can afford to spend. Performance nowadays goes up roughly comparable to actual value of cards. For example, a single GTX 760 2G is a little bit better than a single 580. Not even close to better than SLI 580 though. 760 2G costs $250 now. So, if you went with this lesser card, but did SLI to make it hum, you'd be out $500.
Any single card solution is OK, but not much of an upgrade for the cost. GTX 780 3G, also $500. Can't hold a candle to SLI 760 2G, slightly better than SLI 580 1.5G, but not enough better. Maybe if you sold the 580 for $100, so it only cost $400. And planned on SLI in the future with another $500.
Single 770 is just about even with a SLI 580. Again, hardly can be considered an upgrade, if it costs $350, but maybe it's worth it if you sell the 580, and look toward getting another 770 later.
780ti: total waste of money. If money is tight, you never buy the best card because they get their 'best of breed' surcharge. $750. Not even close to worth it, considering I can get SLI 780 for $1000 which would smoke any single card. Or even SLI 770 at $700 that would smoke a single 780ti.
One good link for SLI review:

Also, if you are buying as an upgrade now, and not as a stopgap, I think you would be best served with dramatically larger VRAM. Even the 3G 780 cards are no longer viable in my opinion (Watch Dogs is probably only the first), and I would only buy the new 6G version now. 2G cards like the 770 or 760 are right out, I would only buy a 4G there.
So in order of cost, which I think is a pretty good metric nowadays. This does not take into account the possibility of selling your working 580, but it does pay the extra $50 for better VRAM.
$100: replacement 580, since you already have one working.
$300: Single 760. Not really viable, slower than SLI 580.
$400: Single 770. Directly comparable to SLI 580, not really an upgrade, but maybe looking at SLI later.
$550: Single 780. Workable. Not as good a bump as preferred, but pretty good.
$600: SLI 760. Nice actual upgrade. Roughly comparable to a Titan.
$800: SLI 770. Very nice upgrade. Better than a 690.
$1100: SLI 780. About as good as it gets and still be considering 'value'.
Since you are doing Surround now, the SLI 580 may no longer be good enough, in which case you'll have to consider if you'd prefer to upgrade now. Anyway, hope that helps.

Not really... if you are using 3D Surround or 4K (probably). If you are stuck on a 1080p /1440p 3D Monitor 780Ti SLI is a waste of money and power/resources.
But if you are a surround gamer (like me) that awesome 60fps in 3D Surround is pure awesome;)) Depends what you really want.

And, at the moment, it's a total non-starter in my opinion, because there is no 6G version of 780ti.

Now that I've got the Titans, I just set everything to max (except maybe SSAA) and enjoy the games. I figure I've probably saved dozens of hours of tweaking by now, and lots of frustration. On paper, my Titans are about the worst bang-for-buck you can get. Yet I couldn't be happier about the $3000 I spent.
Of course, it all depends on your commitment to the hobby and your finances. I count myself lucky that I have a hobby where a guy with a below-average salary like me can comfortably afford the best. If I was into motorbikes or sailing, things would be different.
Here's a comparison in several games, and several resolutions comparing a GTX 590 to a single 770. I'm using the 590 as a proxy for SLI 580.
In general, the 590 is about the same as a single 770. It's faster in some games, slower in others. You can also make other comparisons there to different options.

SLI 580 vs. 770:
Seriously behind in Company of Heroes 2.
Moderately ahead in Crysis Warhead.
No real difference in MetroLL, Crysis3, Bioshock Infinite.
I still stand by that earlier comment that it's not an upgrade, more of a straight trade.
For VRAM usage, there are 3 games now that can use more than 3G:
Daylight
Watch Dogs
Wolfenstein
I pretty much did that last upgrade, where I spent $850 or so for SLI 580s, 3 years ago. No real regrets, it's been a terrific combination, and has played everything I wanted until now.
Now though, same idea of "time is more valuable than money", different take. Since I do contract work, any time I spend working is time I don't get to spend playing. So, if I spend $3K for a TitanZ, I need to do a contract to pay for that. If I don't spend anything and keep my SLI 580, I don't have to do a contract. I prefer my free time now.
