I say 560ti because as mentioned it is a non inconsequential amount faster than a single 580 and if you are actually refreshing higher than 60Hz then that would be welcome. Most of the time I would say go with the single GPU even if it means 55 fps rather than 70 fps because of the 60Hz limit, but in this case SLI 560ti should give you the best chance of getting the most out of your extra 60Hz for the money.
And what if the 1GB memory becomes a bottleneck? Then the 580 would eat it them up no matter how fast they are.

GTX560 Ti SLI vs GTX580:-

- BFG 1000W can handle both without problem. Both solution get 1 point.

- AW2310's resolution of 1920x1080 means 1GB VRAM of GTX560 Ti is enough and 1.5GB of GTX580 does not add much benefit. GTX560 SLI gets 1 point. GTX580 gets 0.5 point.

- 3D can cut framerate in half and this means high graphics rendering power. GTX560 SLI is faster than GTX580. So, GTX560 SLI gets 1 point. GTX580 gets 0.5 point.

-Later down the road, GTX580 can team up with a 2nd card while GTX560 SLI 's upgradability is nil. GTX580 gets 1 point and GTX560 SLI gets no point.

Summing up: GTX560 SLI has 3 points vs GTX 580's 3 points. A tie.

So, as OP already has a GTX580 SC, I suggest staying put.

Couldn't have said it better myself. This is probably the smartest thing to do IMO

I have 2x 560TI's running atm, but i have the 2gb version.

If you were to go SLI 560Ti's the only way it would be viable is for you to get the 2gb versions.

In favour of SLI 560TI 2gb's...

~ This solution costs the same as a single 580 and offers an approx 20% gain in performance (in games with good scaling)
~ Ability to run NVSurround (only 2 monitors per card with NVidia, so apart from the 590 you will need an SLI sollution.)
~ 2gb of effective VRAM, which is greater then a single 580 1.5gb (were you to get a 3gb version, this point would be invalid)
~ Good stand in until kelper arrives and the resale value should be higher due to 2gb being rare.
~ If, for some reason, a card needs to be RMA'd, you will still have a card to utilize
~ 560Ti's are known to be good overclocking cards (dependant on manufacturer)

In Favour of Single 580... (i would recommend a 3gb at this point as 1.5gb can be a bottleneck)

~ Less power draw (SLI 560's will need a 750w bronze 80+ with SLI ready as a minimum, recommended 850w 80+ silver to be able to run SLI 580's in the future)
~ Less heat as cards in SLI run hotter as a rule of thumb... (i have non-reference cooling and my top 560Ti can get to 85c during furmark, it will never reach this in real-world performance)
~ Oppurtunity to buy another card in the future for SLI
~ Will run games with poor/no SLI support to its fullest potential
~ Less Noise, dependant on cooling solution (Ref/Non-ref)

I hope i have helped in some way...

If you require any bench's or link's, let me know, as i researched this very thoroughly before i bought my graphics cards!

Cheers,

Ishi

P.S: My SLI 560's run BFBC2 all on high with HSAO on and MSAA at 7, resoultion 6060x1080 at an average of 50FPS I use a solid 1725mb of VRAM

if he's only using a single monitor @1080 1.5gb will not be a bottleneck. Obviously if he goes higher more would be better..

Thread Starter 
Just to update. I'm sticking with my one 1920x1080p 120Hz monitor. 3D vision but not Surround.

Only reason I brought this up was because due to my motherboard and mid-tower case I have to SLI the cards sandwiched together without any space between them in PCIe slot 1 and 2. I wish I had some space as this would be a no brainer as I'd just SLI my 580.

I'm worried the GTX 580's temp when full throttle for me will go up 10-15C higher. Currently I get to 83C highest at full throttle. Which means my top card can get up to 93-98C possibly...to hot for comfort and 95C a threshold for me I'd rather not pass or be at for long periods of time.

MSI GTX 560ti TFII cards run approximately 20C cooler, due to better cooling soluiton and less voltage. I'd be able to handle the 560ti in SLI together. The heat would dump into my case as opposed out the back high flow bracket but I've got pretty good air flow and enough air blowing inside to keep things cool.

However I've not made up my mind and just getting a pulse on what others think regarding which option might be best. If the performance isn't that great of a difference then I'm going to stick with the single GPU card and wait out till Keplar. Might end up just upgrading to two mid-level 600 series cards at that point.

If I did switch to two GTX 560ti's I'd end up selling my one GTX 580. I'd end up losing some money on the deal so it's something I'm trying to out weigh. So far I've not run into any problems gaming maxed out and 3D is playable gaming as well. I figured if it was a big difference I'd pull the trigger, buy a new MSI GTX 560ti TFII, sell my 580 to buy a second 560ti. OC them to 1Ghz and be done for the next two-three years.

The poll was to gauge the community, not just for me but possibly others thinking same thing. I realize each person has different scenarios which choices would vary pending each owns situation.

Thanks thus far for your opinons and taking the poll. So far I'm leaning to staying put till Kepler and reaccess my options again at that time.

Id go with single 580
This is one of the few times I'll actually have to argue against TPU!

This was a launch day review, and there were clearly issues (either with the driver or their test setup) that caused some significant outliers in their benchmarks.

Check out the results from Call of Juarez. SLI 560 Tis barely perform better than a single 560 Ti at 1050p.

The same can be seen in the Riddick bench, where the SLI 560s run equal to a single 560 at 1024x768.

AND most notably Farcry, where SLI 560s score the lowest in every test from 1050p up!

I love citing TPU charts as much as the next guy but this is one of the few times their results were skewed by quite a bit. The "10%" overall performance stat, should really be between 20-40%:

http://www.guru3d.com/article/geforc...i-sli-review/4
http://www.hardocp.com/article/2011/...c_sli_review/8 (the 560s in this one are very slightly OC'd @ 880/1750/2100)

Just wanted to clear that up!

As for the OP's poll, I'm of a different mindset than most it seems. I tend to look for good price/performance from my card(s), and prefer to buy the power I need up front. IE, if I'm going to run SLI (which I have for my last 3 builds) I get it all at once, instead of buying one card and waiting months/years to add a second.

People talk about upgrade paths available from having a single 580, but I don't see it as being much different than upgrading from a multi card setup. Sure, someone with one 580 can just buy a 2nd one and toss it in. But someone with SLI'd 560s can just as easily sell them off and put that money towards their next purchase. I don't see the distinction.

All that said, Arizonian, since you already have a 580, I'd really just keep it. Like you said, you'd probably have to sell it at a loss, and while you would get a significant performance boost, you really don't want to bother running multi cards if you don't have at least 1 space between them. The heat will absolutely kill temps on your top card, even with the cooler running 560s.

If Nvidia keeps their promise, Kepler is only 6 months away.

overall, i would say a 580 just because it will be about the same and its less hassle.

especially after the guy above me's post.

Single GPU > Dual GPU

Remember, you can always add another 580 later on. Once you get SLI 560's, that's it. You can't go any further from there without changing GPU model.

So get the single 580
