Thats because dual processors (in general) increase the multitasking
ability of the system, not the peak speed.  Thats you you generally see
multi-processor systems in servers, where the load typicaly consists of
many seperate, concurrent processes.  The OS can then run unrelated
threads on seperate processors.

Applications that are designed for it can get a performance boost by
running concurrently on both processors, but generally the thread
scheduling is left up to the OS.

So, unless you typicly run with a high average processor utilization,
multi-processors systems are probably not going to be as cost
effective for you as a faster single processor system.
