My guess would be the same as the gtx 6xx microstutter situation.

 

[BrightCandle]

Its actually a mixed picture. In a lot of cases its better than a pair of 680's but in at least one game I saw pcper test they had more some problems. Techreport as far as I have seen haven't tested them in SLI and pretty no one else does this well so I can't say much for the other results.

Not really enough information IMO, pcper don't test enough different games but from what I have seen it looks decent enough.

Frametimes in the following review look promising:

Absolutely, and that link is to the Metro Last Light bit (where they identify problems linked to the game itself). Check out a truly well-made game like Tomb Raider. Absolutely beautiful: http://www.guru3d.com/articles_pages/geforce_gtx_780_sli_review,8.html

Use a single card?*scratches head*

just to add ive used both single card every time imo.

But what do they mean by "With SLI we see scene shimmering..."?

Missing frames would be my guess, because frametimes look good.

It's a shame Nvidia hasn't educate them enough to draw their conclusion from gathered data, because with FCAT they have everything they need.

If you are hypersensitive to tearing, <60fps, frame spikes, ect.

IME i've been much better off single card and settings that pin me to 60fps. Hardest part is accepting you won't be able to run with max details. Though locked to 60fps at settings below, but close, to max is a better alternative.

So the titan or the 780 and play at Very High (high if needed) instead of ultra in the most demanding titles.

 

[moonbogg]

The 60fps target has become an absolute necessity for me, as it appears that I've reached a new plateau of hypersensitivity to framerate fluctuations below monitor refresh rate (http://forums.anandtech.com/showthread.php?t=2315316). My only strategy is to meet that target at all costs. The only way to do this is with multiple GPUs. I suspect it'll backfire on me though, the hypersensitivity will undoubtedly apply to AFR microstutter too. :|

Don't be so sure. I am highly picky myself. So picky infact, that I switched to a 120hz monitor and now I can't go back to those slow, slugish 60hz monitors. They look like absolute crap compared to 120hz.
I use 670's in SLI and "microstutter" is a non issue. I try hard sometimes to spot it and I can't see anything. GTX780 SLI will make you one happy gamer, thats for sure.

I have moved to 120hz/3D gaming, because I learned that this sensitivity was causing me nausea. After the switch, I've found that if I hit 80+ FPS, I do not get nauseated in 1st person games anymore. At 60+ I start to feel nausea after an hour and when FPS dip once in a while, I see it immediately.

The interesting thing is, I ended up loving 3D Vision gaming. So now I have to maintain 60 FPS at all times, which takes the GPU power of 120 FPS. And I still have to take breaks after an hour or so, as 3D Vision forces v-sync, or the effect is destroyed.

SLI is generally very good. Maybe not perfect, but it is good enough that it doesn't cause microstutter very often.

The 4770k does not OC well at all. If you have a reasonable OC on that 2600k, you won't see much if any benefit from the 4770k. I'd dual 780's before upgrading.

http://www.tomshardware.com/reviews/core-i7-4770k-haswell-review,3521.html

They found the average OC is only 4.3-4.4k, where as the 2600k can get much higher. As you can see by the benchmarks, the 4770k is not much faster than 2600k at stock speeds. If you add in the OC potential, there may not be much difference.

I don't OC.

Why are you getting K series processors?

OC'ing would net you a greater improvement in performance for less money. Not that it will make much difference, of course. You're going to be GPU bound well before you're CPU bound at 60Hz. Skyrim with a 3570K and a 780 averages 145fps.

[bystander36]

Every game is different. Some are CPU bound, others are GPU bound. If you are serious about limiting CPU bound issues, OCing is the only thing you can do. You don't even have to push things hard either. As long as you are not pushing the limits of stability, you do not have to mess with it again. It will not be a reason for any issues in games unless you have pushed to the edge of stability.

If you want to always have high FPS without dips, you cannot do it without some OCing, even with the 4770k.

As far as the 20 FPS increase...you do realize the test was with the integrated GPU's. They have different integrated GPU's, so that was the performance change. It was not the CPU that increased performance. You may only see 5 more FPS when using the same discrete graphics card in the most extreme cases.

 

[yefi]

Whether or not I'm CPU bound varies not only by game, but by areas within a given game. You can't say "Skyrim is GPU bound" or "Crysis is CPU bound" - they be either from map to map. In Skyrim I maintain 60fps for the vast majority of the game, but there are still a few trouble areas, some CPU bound and some GPU bound. Here is one clearly CPU bound area:

That's the kind of anomaly I'd expect to clear up with the 4770k.

But what were your cores at? If you were seeing 100% or close to it, then sure. But it could conceivably be another bottleneck, like memory bandwidth.

Where do you get that idea from. They're using a GTX 670. They wouldn't be stupid enough to use the CPU for the CPU testing. Those aren't the IGP benchmarks.

I don't know which benchmarks you were looking at, but the link I gave was indeed comparing IGP's. Look at the heading of the page: http://www.tomshardware.com/reviews/core-i7-4770k-haswell-review,3521-7.html
Those are really low scores for medium in Skyrim if it wasn't with IGP's.

 

[FalseChristian]

My 'old' i5 2500K at 4.5GHz will not be a CPU bottleneck when I grab 2 GTX 750 Ti BOOST SLI. Or even 2 GTX 780. The i5 2500K at 4.5GHz is still a great CPU for gaming.

That's not even my link. I linked the HC review and:

You responded to my link, so I assumed you were talking about the link I gave.

Edit: I did take a look at the link now. Keep in mind, the FPS went from 142 to 172. That is only about a 15% improvement in speed. When looking at a min of 53, you can expect about 7-8 more FPS. You could make that difference up with OC potential.
