i5-4670K or i7-4770K - When is GPU Bottleneck not a Factor?

I've picked up a HAF X case and have decided with the ASUS Hero MB. I was going to go with a i7-4770K figuring it is only $100 more than the i5-4670K. I have looked at comparison reviews (often mixed) and read comments in the forums and it seems like it might be $100 wasted as the i5 seems to be able to perform nearly as well as the i7. Several reviews have associated the system bottlenecks with the GPU with games at high resolutions (1920 by 1080).

So, I am wondering at what point does the GPU not become a limiting factor. I am hoping to go with two - R9 280X in crossfire mode. I have tried looking up 3DMark results but it can be a little confusing when you aren't sure how the systems might be OC'd when doing the comparisons or whether other factors (memory) might be influencing the results.

I guess the other thing is, does it really matter for a system like this if I only play on some minor OC's - 10%, do some moderate gaming (CIV5, WOT, Skyrim...), and office stuff.

Thanks

Expect to fill out the system with
128 or 250 GB SSD
Seasonic PSU X-1050
16 GB of decent memory (G Skill, Corsair)
 
Hello... you will have 8 cores vs 4 cores available with the i7 due to hyperthreading, in the Windows Task Manager/Performance screen... Some applications such as Games will not use them, but Windows, Office, Graphic and Scientific apps will.
Get a 240 gb SSD or greater for your BOOT drive, prices make it worth it at this point in time... in the Life Cycle of my CPU, I will upgrade my GPU about 3 times, Performance, Technology, Price and features seem to out pace CPU changes.
