What we do in our setup is monitor CPU utilization (average across all
cores) in conjunction with load (and of course graph both).  You could
even have a separate check to monitor the CPU utilization of the
busiest CPU.  You could adjust your load thresholds in accordance with
the number of processors.  Then when/if your load hits a threshold,
you can check the CPU utilization graph to see how it compares.

I would think that the load average would be easier to interpret if
the applications running on the server are multithreaded (and load is
distributed evenly across the cores).
