Low latency is interesting when you're tweaking the VST in real time and want to see how it affects your recording. With enough CPU power and a good audio card, this is doable even with a complex stack of effects.

I guess it could also be important when using external processors.

Yet this has nothing to do with low latency. You can have a decent realtime preview with ~120ms latency, which I use as a limit for instantaneousness.

Low-latency is good for performance, as in, for performing live. And that's it (Then again ask any church organ player about latency.. He has ton of it)
