Agreed that the OS should be able to handle it the best it can.
Though somtimes you have processes that are more important than others and you want to maintain a level of performance for that (application) process.
An example might be if other (applications) processes hog the cpu's, therby lowering the level of performace of the more important process.
This might be unacceptable which is why processor affinity is required.
These utilities are very valuable on scale up boxes versus scale out where problems like this are frequent.
