Hello, I'm building my first rig, and I was wondering if its better to buy 2 EVGA GTX 560 Ti 1GB Superclocked or a single EVGA GTX 670 2 GB Superclocked, the price comes around being the same here in Germany, and like must of us I want my money's worth....as well Im interested to know how much power will I need....

Im putting together a core I5 2500k to be overclocked from 3.3 Ghz to 4.5 ghz on an ASUS P8Z68-V PRO/GEN3 - Z68 with 16 gigs of ram, inside a NZXT phantom..... would 800 wtts do the trick???

Thanks in advance

My choice would have gone to gtx 670 2 Gb.you can get the other too.but 670 will be obviously a better choice.again you are getting a chance of SLIng another 670 later and that will give you double advantage.so don't think twice .then 800watts should be enough but if you can manage ,look for a 1200watts for a hard overclocking.this will make your rig quite invincible.

Definitely go with the 670; it's performance is significantly higher then the 560 Ti.

The Sli is a great setup; but it has limitations. It has relatively low VRAM. Which may create bottlenecks with high-resolution / multi-display setups with all the render effects on. The Sli configuration is capable of out performing the GTX 580 in several instances; but does fail in other instances.

Where as the GTX 670 is already 10% faster then a GTX 580 at stock frequency. Once it's overclocked it can essentially hit 40 to 50% better over the 580. Which is a huge gain; especially with lower power consumption and it's ability to multi-thread processes.

The 670 is possibly the best card on the market. It's low price and ability to overclock to the 680. To essentially be 5 to 10% below an overclocked 680 for significantly less.

Plus, when the card you feel isn't performing up to par. Simply buy another one in three-six months as new cards are coming out. Which will help extend the life of your rig far better then the 560 Ti SLI configuration.

What was said here is right, but...
unless you plan to use it for some CUDA based calculations. Video transcoding for example.

Right now, SLI 560 Ti would be a lot faster. Probably 50% faster.

However, the 670 has advantages. Single cards are more reliable. It has 2gb of VRAM. You can SLI later.

Really depends on the games you'll be playing and your monitor. If you are at 1080p, then a 670 is going to max out all games anyway.

I vote for the 670 as well, seeing as I have 2 560 Ti's. The heat is ridiculous in comparison to a single card even with 2 slots in between them. Power usage is higher as well.

Reliability-wise:
I have had 1 issue in games related to SLI and it was fixed when Nvidia released the SLI profile for Alan Wake. No detectable micro-stutter in any game I play.

For the love of God, please do not get 2 x 560ti's...

I have 2 Gigabyte SoC 560ti's like Cliffro as well. I've started to notice stuttering and after buying and playing BF3, it was horrible. I've turned off SLI and using 1 card atm and I ordered an EVGA 670 FTW yesterday and I plan to sell 1 card and use the other for physx / 2nd machine. Look at benchmarks, the performance of both options are the same, not 50% in favor of the SLI config...

I'm just over the hassle, bring on lower noise, heat and power :)

The proposed SLI setup you've essentially chose is quite powerful. The benefits:

1. Great performance
2. 5-10% Boost over GTX 580 Single
3. Average of 15 FPS increase over a GTX 580

Downfall:

1. The noise and heat generated
2. A stock GTX 670 attains 20 FPS minimum against GTX 580 across the board.
3. Fermi Architecture VS Kepler

An overclocked GTX 670 will have an increase of 50% performance over a GTX 580. With significantly less power; the performance per watt is significantly better. (Note my percentages are in reference to performance per power consumption).

The ideal choice is the 670; it can handle any game on the market at full. The massive amount of overclocking headroom is a massive bonus as well.

Plus you can Sli later; so it's longevity will be far superior. The 560 Ti in SLI will be on a level playing field with a stock 670; but overclocking the 670 should give the 670 a performance edge.

Benchmarks found:

Hopefully that helps; at least you'll have documentation and some more explanations from members. That way you can make your own decision; but hopefully this at explains why several would lean one way over the other.

Just my 2 cents here. Having recently upgraded from a 560ti SLI setup to a reference 670, I can conclude that they perform very similar when benchmarking via Unigine Heaven 3.0.

I keep a spreadsheet of benchmark results and when looking at the numbers it is surprising at how close the scores are.

Setup: i5-2500k @ 4.4GHz, 8GB RAM @1600Mhz on Windows 7.
Heaven: DX11, normal tessellation, high shaders, 4x anisotropy, 2x AA, 1920x1080

560ti SLI: voltage @1.025, core clock @920, shader @1840, memory @2125
FPS min = 37.4, max = 186.8, avg = 81.6.
Score of 2054

Zotac 670: voltage @1.100, power target @115%, GPU offset +140, mem offset +120
FPS min = 34.4, max = 193, avg = 81.7.
Score of 2058

Take this info for what it is worth and nothing more. This does not reflect in-game performance which is noticeably better with a 670.

Yep, I thought raw performance would be the same...

I have replaced my 2 560ti's with the 670, I have both cards sold and BF3 is cranking on ultra + 4xMSAA and 16xAF. Perfect :) 
July 28, 2012 5:58:56 AM

I have to agree with the 670 I have dual 560 Ti's in SLI and am running into bottleneck problems running games like Empire total war on one 24inch monitor. Make sure you get a model with a minimum of 2GB VRAM though. As the VRAM will make the difference in the setups not so much the clock power of either setup. The VRAM makes all the difference "maxing" out a games image quality.

Hello, from a gamers perspective:

I've never had problems with BF3 and SLI, as long as you remember to force disable vertical sync from the nvdivia panel and set it to single monitor performance. For some newer games that does'nt support multi gpu rendering, you may need to enable it by force through nvidia panel, and for old games you need to disable SLI completely.

I've had two SLI setups in 5 years - So I made your decision twice and I would ALWAYS go with SLI. Especially if you have a tight budget, and no plans about getting another card within 4 years. Because by then you will want to get a new comp anyway. The more you pay per graphics cards, the less you get.

My old setup had 2xGeForce GT8800

My current setup:
ASUS P9Z68-Vpro motherboard (PCI-expres SLI mode is 8x8)
Core i7-2600
2 Asus GTX 560TI (clocked to 900mhz) in SLI

And only yesterday 07.08.2012 I assembled my friends new computer:
Sabertooth Z77 motherboard
Core i7 3770K
Zotac GTX670 AMP edition

We have the same RAM and HDD
16GB Corsair vengeance - 1600mhz FSB
Corsair performance pro 128GB SSD.

We both play BF3 on 1920x1050pixels monitors (22" and 24"). yet my machine is running it slightly better (About 10-15 fps) - with the exact same gfx setup (everything on high, 4x anti-aliasing, 8xanisotrophic) - enough for my friend to regret that he didnt go with 560tiSLI instead.

Windows experience index gets me 7,8 in both graphical settings - my friend gets 7,6 and 7,5 which messes up his otherwise flawless 7,9 score. (But yea.. as if windows experience is accurate) - actually it's pretty damn accurate.

I don't doubt the other guys statements: If you have a huge monitor resolution, the 560ti might not be as good, I haven't tried.

But, if you are a gamer who uses 1 normal-sized display, without needs of more than 8xantialiasing - I'd go with SLI.

Only my personal experience.

You should overclock the 670; once you overclock it he should see better gains. You both have a nice setup though.

I just finished playing Crysis 2 (maxed out) on my 22" 1680 x 1050 resolution monitor, with my brand-new second GTX-560 in SLI.

It may be my modest resolution, but the SLI setup is cutting through the game like butter. With the single 560, it was ok on "extreme". Now, with two in SLI, it's crazy-smooth on ultra.

It's quite the upgrade over the single card, but I have never played on a x70' or x80' card though.

August 10, 2012 12:02:43 AM

You can pick up the Gigabyte 670 for pretty cheap and it has a great cooler. My overclocks are amazing. with a 12% OC, my temps didn't break 60C when maxed (I also have good case airflow). I would say get the 670 with a Z77 MOBO and some PCI 3.0 slots. later on pick up a second 670. At Bf3 on Ultra with everything maxed and my OC, I can pull 100 fps avg (don't worry I use Vsync when not benchmarking).
August 10, 2012 3:40:22 AM

Because you own one... or do you just come onto forums and make unsubstantiated claims? Why don't you go read the Tom's review of the 670 or 3dguru or any other reputable tech sight? Or better yet, go buy one and test it before you just spew your *** everywhere. I've had 0 problems with mine.
August 10, 2012 2:10:24 PM

For Future proof, Suggest Going with the 670.

Not to add to this enlarging flame war that is occurring. But in what way are they cheap? Buggy?

A few launch glitches for a completely new architecture isn't uncommon, but seems to be patched quite quickly. A graphics card right out of the gate achieving the overclocking, power consumption, and overall performance in the top tier of performance isn't considered cheap.

If buy cheap you mean very reasonably priced; and competes with the GTX 680 and 2nd Gen 7970's at a cheaper price point- then your correct. A single 560 Ti will not compete with a single GTX 670. A SLI 560 Ti will compete with a 670- but will loose the benefits of Kepler's architecture, higher power consumption, lower overclock results, and the enhancements for gaming that were integrated to the 670 / 680.

Yes, the Fermi architecture appears to achieve high and competitive benchmarks. Which is drawn to it's ability to calculate data very, very well and better in some cases then the 600 Kepler Series. The 600 series, 670 / 680 are better for gaming and achieve better results then it's 500 series counter-parts.

Usage is a heavy factor- but the overall value of a 600 series card is better. Because you'll have next gen features; then you can SLI later to help system longevity.

But when you provide a comment, please remember- the goal of post isn't to slander but to assist the community. Hopefully my response has helped.

I completely agree. GTX 560 TI's in SLI are faster than one GTX 670. I bought the same GTX 670 the OP is referring to and regardless of overclocking, the twin TI's are noticeably faster. I returned the GTX 670 to NewEgg in favor of a second GTX 560 TI because I wanted more and never looked back. I also saved $200 at the time by doing so.

BF3 maxed out..
GTX 670 Peak FPS 101
Average FPS 65
Min fps 38

2X GTX 560 TI 2GB Peak FPS 118
Average FPS 95
Min FPS 67

My WEI for the GTX 670 was also 7.6 & 7.5 as you stated whereas my WEI with my twin GTX 560 TI's is 7.9 for both. I have 2X MSI N560 GTX-TI/OC 2GB Twin Frozr in SLI and my GPU comes at 880mhz from the factory. I am able to safely run these cards at 985/2203 but there really is no need to go beyond the factory settings when I get a 7.9 WEI.

My rig.. SLI not working with the FX 8150 is a MYTH.
FX 8150 @ 4.7ghz cooled by Antec H20 920
ASRock FATAL1TY 990 FX
8gb G.Skill Ripjaws 2133 @ 2133
2X MSI N560 Twin Frozr II GTX560-TI 2gb.

I think the OP would be happy with the one GTX 670 and it would be cheaper than buying two GTX 560 TI 2gb cards. I wouldn't go less than 2GB on the memory. He'd also have an upgrade solution down the road as well. If I didn't already have 1 GTX 560 TI, I probably would have kept the GTX 670.

One other thing to consider. Sometime new games don't support SLI right away. I still can't get Sleeping dogs to work in SLI so I'm stuck with only high settings using one card for PhysX at the moment and I refuse to play the game until I can completely max it out. Just the way I am.

The GTX 660 TI's are out and are about $300 each. Two of those in SLI would be beastly compared to one GTX 680 at the same price.

This thread has been very useful, as I recently purchased a second 560 TI superclocked for $200 (Amazon, used) and have been using one for the past eleven months. If this performs 'on par' with a GTX 670 I'll have saved $200. However I see a lot of people say "Problems at huge resolutions."

Can you please define 'huge resolution'? Is 720 or 1080p considered 'huge resolution' or is that referring to something much higher? My monitor is a 42" HDTV and this is for playing Skyrim and Borderlands 2, hopefully on ultra settings.

Huge usually refers to 2560x1600(maybe even 1440) and up. 1080p is almost the default unless you have a CRT or smaller LCD/LED monitor.

Ah fantastic, so my 1920 × 1080 will indeed be superior on the dual 560 setup. I'm quite happy to hear that, and I'll be itching to set it up when it arrives. I can already spin in Skyrim without a significant frame rate drop, I can only imagine what the boost will be.
September 11, 2012 5:51:08 AM

Nice story, however, WTF are you talking about? When I had a 560 ti it was 7.9 across the board in WEI, 560ti SLI should definitely be there also, not 7.8, and the GTX 670 should also do 7.9 no issues since, for instance, my last card was a gtx 570 and that got 7.9. Unless your running a 560 or lower, you should be maxing WEI. No middle end 600 series nvidia should be lower than 7.9, let alone a higher end 670.. maybe you had a type. Maybe your cpu was bottlenecking your GFXs? not sure why under max WEI. To top it off I got a 27 inch samsung and still 7.9 with every card I have had since 560ti. Peace

Doesn't matter, WEI is the most useless measurement system for computers ever seen. You want a measurement, run a benchmark.

But say i already HAVE a MSI GTX 560 ti, and considering an upgrade. should i just get the 670 to replace the 560ti (which i could pass to my younger bro to use), or do i just get another 560ti (which is cheaper than buying the 670)?

Any advice?
