I just don't see enough of a difference to justify the extra time...unless you need to be able to animate a fly-by along the surface of the circuitboard, or something.
I had to get on to one of my designers once, for modeling something down to the threads on a bolt...when the final rendering the head of the bolt would only be 1-3 pixels! Since he was an hourly worker, I felt that he was wasting time... but if you are just doing it for fun, then it doesn't matter.
