Firstly there wont be CPU cooler in box for 7700k also cooler is depending on the max overclock you are will to do. But a 240mm AIO will be sufficient for most overclock settings

hey i noticed that you have selected a z270 motherboard and i7 7700 non-k for the build. so ill rephrase the answer
the performance bump is significant from going to 7700k with max overclocking your cpu die can handle. Also you are already going with the z270 MB then the only price of CPU and cooler is added then its definitely a good thing in long run.
