Cons & Pros of buffering vs no buffering

Something I've been meaning to ask about is the effects of buffering vs no buffering.

My usual setup is 50hz + low latency vsync + minimum sound buffer + no buffering.

With no buffering set it produce absolute minimum input lag, however on occasion, 1 video frame seems doubled which I presume is fail safe for audio buffer?

If I set triple buffering, there is of course more input lag, however I think there are never any doubled frames & the audio seems to have even less latency then with buffer disabled.

Is this about right?
My main reason for asking is the possibility of 'triple buffering' being the best option for video recording - since there are no doubled frames, tighter audio & input lag is irrelevant.
