i5 2500k OC @ 4.5 with GTX 980 Ti 2 way SLI......

[Samsonx]

I game at 1440p resolution...

Will there be bottlenecks? I keep getting stuttering in my games so just wondering.
Will upgrade to i7 6700k If its my cpu. Will there be any noticeable improvement?

I suspect there will be bottleneck, yes. Btw, what motherboard?

I would think their not a CPU problem. I ran sli 970's with a 4.8 2500K with no problems at 2K resolution. Depending on the games the SLI could be the problem or net connection.
