Would I need a better heatsink?

[The Domino]

I am going to build my first gaming pc and I am going to get this cpu. http://www.amazon.co.uk/Intel-i5-4690K-Processor-Graphics-LGA-1150/dp/B00KPRWB9G/ref=sr_1_1?ie=UTF8&qid=1424007390&sr=8-1&keywords=i5

I was told that the heatsink that comes with the cpu will be fine unless I overclock. But will the heatsink that comes with it be ok for running games like far cry 4 on highest settings for a long period of time.

The stock cooler will be fine at stock speeds but do NOT try to overclock with it.
