It all depends. If you you want to take a close-up portait, then
probably yes.
However, if you are trying (like thousands do every day) to illuminate
the arena at major sport events from the last row or like the one
hopeful photographer who attempted to illuminate Mt. Rainier at late
dusk from 20 miles away using the build-in flash in her P&S, then no.
The question you should really be asking: is the effect of a flash
desired. And if yes, will it provide enough illumination to reduce the
ISO to a usable level.
BTW: there are other ways to reduce the ISO, e.g. long exposure, using a
tripod if necessary, or a large apperture.
