As the notebook user interface and the kernel are separate processes, and the OS always has other threads of execution going on as well, there is certainly a nonzero benefit to having multiple processors. But the kernel has only one computational thread, and so computations cannot be distributed over multiple processors by a single Mathematica kernel. However, computations would benefit directly from multiple processors if you use multiple Mathematica kernels which communicate with each other. Wolfram sells an application called Parallel Computing Toolkit which provides tools for doing this (as well as for parallel computing tasks by processors in separate systems connected via network).
