My question is exactly what I stated in the title; Will an i5-4670k @ 4ghz bottleneck 2x 980 ti's in SLI?

Thank you

Actually it might depending on the resolution. My 3570k @ 4.5 GHz bottlenecks 1 980ti @1080p. However I doubt you will have this problem at 4K. People need to become aware graphic technology is catching up CPUs. A 5960X bottlenecks 3 Titan Xs (Aka 980ti - 5-8% performance). If you are playing BF4 or other CPU intensive games you will experience bottlenecking unless you play at 4K or similar high pixel counts (like triple monitors)
 
The i5-4670k (being discussed) and the i5-3570k (you have) are totally different CPU's. You have the 3rd Generation i5 and we are discussion the 4th Generation i5's. The different architecture makes a world of difference, regardless of clock speeds. In some cases, OC a CPU/GPU can actually reduce performance. So you are not really comparing apples to apples here...

Yes, it can depend on your resolution.
I happen to have a 4670k at 4.0ghz and Titan X in SLI, and can tell you that unless you are playing at 4k, you will have severe bottlenecking issues.

Even at 1440p I bottleneck pretty hard.
Although, zero problems at 4k.
 


Bottlenecking is often mis-used, but that is a different discussion. Bottlenecking refers to one component being slower than another and limiting the power of the more powerful component. Therefore, it makes no sense that you would "bottleneck" on lower settings and perform better on higher setttings.

What you are saying makes no sense...

Actually, it does make sense.

The higher the resolution, the higher the load on the GPU will be. The load also increases on the CPU but not nearly as much.

Example: If you were to game at 20k, the vram of your GPU would not nearly be enough. The GPU wouldn't even be able to load the game because its memory is full. The CPU will not be the bottleneck in this case. At a lower resolution though, the bottleneck will occur on the CPU.

Check some benchmarks and find out for yourself.
