Texture Streaming - purpose

[eco_bach2]

Can any render experts chime in, when and why would you enable texture Streaming?

Texture Streaming Overview

I understand that it enables more efficient use of memory.
Does that mean it is primarily useful when targeting mobile platforms and if you are targeting desktop you can safely ignore?

You would enable it on every project, where having all textures from the same level loaded at the same would exceed video memory budgets.
