It will still run the card no problem, its a great CPU.

It won't bottleneck it in the majority of games in normal resolutions like 1080p. If we are talking two or three high res. monitors, the GPU will actually be the bottleneck.

EDIT: check out this page from a recent review on the new AMD FX-8370 series of CPUs. THe 4690k and 4790k are used to compare them. They also use a high end GPU (295x2) and a mid range GPU (R9 270) to show what becomes the bottleneck in certain scenarios. Basically, an i5 4690k @ 3.5 GHz will almost never be the weakest link in any system, in any game for now and the near future.

Some confusion here.

The i5-4690K can run at 3.5GHz but it will run LOWER if not required and can Turbo up to 3.9GHz if needed as well (assuming you use default or XMP settings).

I recommend just using the "XMP" profile which you may already be at because it won't disable any Intel power management (choosing your own settings can) which would probably choose closer to 4.1 or 4.2GHz.

So again, the default is actually 3.9GHz max, or closer to 4.2GHz with XMP and you should simply use the XMP profile.

(Even though you can overclock an i5-4690K as high as 4.8GHz I don't see the point. It would rarely help and just adds to the heat and fan noise.)

it annoys me a little when people ask questions if a high end gaming cpu will bottleneck a video card. You dont really have many more cpu's that are better for gaming than that cpu.
