The title says it all. What is better? 2x SLI NVIDIA 670MX 3GB vs Nvidea 680M 4gb? will be using it for gaming.
Thanks
 
For gaming, 680
For benchmarking, sli or crossfire

From my years of experience with sli and crossfire, they just bring problems. I've built setups with, 7600gt sli, 8800gt sli, 275 sli, 9800gtx sli, 4870 crossfire, 4890 crossfire, 4870x2, 5870 crossfire and loads more. I still yet to see one which doesnt suffer from micro stutter and driver issues.
 
id say gtx 670 m in sli...ive had 2 x 470's in sli and 670's in sli, and i have not had a single issue. no microstuter, nothing. more performance, so thats what id go for.

If you play at low framerates like 40 fps, you might not notice micro stutter anyway or you are the luckiest guy in the world.

why would I play at 40fps running 2 x 470's or 670's in sli? 1080p 60Hz..60fps all day rare dipps, vsynce on, smooth as butter for years now. if im lucky then great, but I don't think im one of few people who don't have thins problem. is micro stutter that common, cuz the last ive seen it was with my 4890, switched to gtx 260 core 216, stutter went away, and have been with NVidia since, over 4 years. (have had 470's and 670's in sli) still, id go with the sli set up if I had the opportunity, with the 670m for the OP.

A lot of people seem to think that 40 fps is very playable, even people with good graphics cards, whom like to max out games like crysis, 2, 3. I too need to play at 60 fps, with vsync and this seems to be the ingredients for micro-stutter. The general theory is that micro stuttering occurs because video cards are forced to share data across the relatively slow PCI-Express bus instead of between their own high-bandwidth connections. This being true of all sli and crossfire setup means that this technology is flawed. I have had a game or two not micro stutter, but im still yet to see a multi gpu setup that doesnt micro stutter on most games. The worst game ive seen for micro stutter is fallout 3, no matter how high the framerates, it still looks like 30 fps. I do believe tho, that a lot of people playing at lower framerates and without vsync are unlikely to notice micro stutter.
 
Had plenty of CF and SLI and never had an issue. Secondly, technically innacurate as if what you are saying is true, microstutter would be evident in 3 gpu setups, which it almost never is. So its not the PCIe vs onboard interface. Thirdly microstutter increases at lower FPS so you have that backwards. Microstutter is also much more common in ATi and is more likely to be a driver issue.

Ive never seen an issue though, so making a blanket statement about SLI/CF being a flawed technology is wrong.

The guys at PC Perspective have proposed a new way to show frames that accounts for these mis-frames (microstutter).

The 670s in SLI will beat the 680, but will be costly.

I agree to above. I don't think there are many people on here who have had sli set ups, and for those who do have sli set ups I don't believe they are having micro stutter issues, since no posts or threads have been made. there would be by those who have them. I too believe that its a driver issue more than anything else, and is more likely to happen with amd. and when I say why would I be playing at 40 fps, is because sli'd 470's or 670's simply wont let you get that low in frame rate, even on maxed out settings, except maybe a few games, like crisis since its poorly written. I just got my 2nd 670 4 gig card by evga, and even though its overkill now, it plays like butter, never dips below my TV's refresh rate (60hz). in the very near future, ill be getting a 47" 120hz Samsung 3d tv, so the 2 cards should hold 120hz or close too constantly for it to truly perform how it is meant to...

.to OP...go with the 2 x 670m's....you will be happy. remember, 670mx are not the same as the desktop version of the 670. so having 2 of them over a 680m would benifet you much more. 3gigs is plenty of vram, so again the 4 gigs on the 680 would be uneeded right now, and for some time yet.

You can understand why i find what you two are saying very hard to believe, to me its like you are saying gravity doesn't exist. All i can say that the aforementioned cards above (plus a few more), definitely do suffer from micro-stutter in multiple different setups. This to me is a lot of cards and i personally wouldnt risk gambling and going sli or crossfire again. I have four close friends who are also pc gamers and for the last 10 years i have built their computers. None of them would go sli or crossfire after seeing for themselves the problems ive had with these setups, so i know im not crazy :P. Im really starting to think that micro-stutter does exist, but some people are more sensitive to its effects. After all, are eyes maybe the same, but they are just lenses, its the brain that processes the images and maybe thats where people differ, i dunno.

Just read this: http://www.tomshardware.com/reviews/radeon-geforce-stutter-crossfire,2995-15.html

670mx is based on a newer architecture then the 680m and uses less power and has better perfomance per watt. (talking about it as a single) The 670mx sli scales very well. Personnally i would go for 670mx for the "gaming and benchmarks". Comes down to you. Bottom line is if u want single gpu go 680m if u want great benchmark score and highers fps go 670mx sli. I belive the 600m series are fermi (with a few exceptions) and the 600mx series are keplar. I see you gus talkig as if the op was askong about desktop graphics cards but the ops asked about the 670mx??? Which is a laptop gpu.

We answered him several times.

We understand the difference in architecture regarding watts, but usually laptops are set by maximum TDP ceilings. So yes, it will be slighting (10% would be my guess) better per clock.

New graphics cards scale pretty well, my 580s are near on exactly 200% in SLI compared to 1 card on the same mobo.

I have never seen microstutter. I have had various setups including a nvidia hacked chipset, crossfire 5770s, 580s (3 at one point), and 8800GT in SLI.

I believe microstutter is being better understood now, as per my previous post.

@Shlouski Your technical ascertions appear incorrect.

So he should go wih the sli xD. If he would come back and actually make a decision lmao. And i only skimmed through the answers quickly.

I think most cards can do 3d gaming, my 680 certainly can, it can also handle 1920x1080, which is the highest more or less all monitors can do at the moment, so not obvious at all. I find it strange that basically all the people i have known in real life whom have had multi-card configuration hated them and had problems, but then people i have never met on the internet talk about how wonderful it is. I have no agenda, i want sli and crossfire to work soooo much, but i always get burnt, if i thought they worked i would buy another 680 right this very second. I just know that i would be on the road to driver issues and more frame per second, but it would look to my eyes like i was only getting half the frames that i was getting with a single card.

Wow, really.

2560 x 1600 is not used? Quite a few monitors are above 1080p.

Even at 1080p, your 680 cannot do 3D. You would have to drop the resolution down below 1080p to 1680 x 1050 and even then it just manages to get the required 120FPS in BF3.

Yes i agree that the multi card setups help with those two circumstances, but this is in a laptop, that likely will be primarily displaying on a 1080p display, so im not so certain the screen resolution will be above that... if it is sure, multi card all the way, but i doubt it will be above that...

Nice copy and paste from Extremetech. But it's not really what causes microstutter.

The reason behind it is that the GPUs render alternate frames, but some frames take longer to draw than others (explosions etc). This means that one of the GPUs has to wait before it can send its data in order to maintain synchronization. Microstuttering occurs when the length of time this takes falls outside of the tolerances required for smooth gameplay. In a perfect world at 60 fps, a frame has to be rendered every 16.66ms, but realistically this never happens. Frame delivery time often ranges from 8ms to 25ms. This is "tolerable" just so long as the larger frame times don't occur too often, which is when you get microstutter.

That said, I've been running SLI on top end cards all my life and never experienced any problems. Nvidia's drivers have always been superb. Before I had my two 680's, I was running tri SLI 580's and before that tri SLI 480's. These setups have always given me stellar performance @ 2560x1600.

2560x1440, 2560x1600, 4K screens just around the corner.
