That is my current build.
I haven't decided on whether or not I want to OC the system, but I have the ability to if I wanted to.
Keeping this in mind, do I really need the cooler that I have in mind?
It seems a bit expensive, especially considering the Intel CPU comes with a fan of its own.
Do you think cooling will be an issue, even if I don't OC???

Thanks

Such a cooler is only really necessary if you are looking to overclock, otherwise one half the price & size will suffice if you want better cooling then the stock cooler.

Personally I like having a good cooler to help with life expectancy as well as dealing with all sorts of ambient temperatures all year round. Ultimately if you live somewhere with cool ambient temperatures as well as have no plan to overclock, then you could get away with the stock cooler.
