What Does High MHz RAM Do?

[piggykid1]

I was wondering why you want to buy high MHz for a computer build and why  it is beneficial?

Thanks!

It helps in certain applications like Photo and video editing.

It doesn't help all that much in gaming unless you are using an AMD APU.

Quite literally it let's the cpu draw and write data to the ram faster.
