The topic is actually quite complex, and results in packet losses.
Since most consumer grade network devices (where network
devices are both the switches, and the device network adapters)
do not include the necessary instrumentation to report, you will
never be able to know for sure.  A peak utilization of even as low
as 30% can see packet loss due to microbursts.  Real networks
are hard to get right, and even the best designed network will
likely see some packet drops (and, in fact, you want controlled
drops), while eliminating unnecessary microburst drops.

The "cheap" solution is just upgrade everything to gigabit networks
and hope for the best (a better solution involves upgrading to gigabit
with enterprise switches with at least larger (ideally settable) buffer
sizes and the needed instrumentation so that you know when you
are seeing drops, but I expect few will follow that path, although I do
like to be able to see the numbers).
