Are Resplendent Chests worth farming?

You can often find Resplendent Chests in the bottom of optional dungeons, and sometimes randomly on the field. Are these chests worth constantly looking for, or is there a cap to the types of items they can drop?

The answer appears to be yes, but with caveats.

There are a number of references to farming Resplendent Chests (I don't personally, so I can't speak from experience) and they generally concede it is worth it in Inferno, if you can't kill Champion or Rare packs. The implication is that the Rare and Champion packs are a more efficient way of getting good items, but some Resplendent Chests are easily accessible so can provide a good way of bootstrapping your own items/gold to compete in Inferno.
