A notebook is merely a repository for code! Using eight cores you will be able to run parallel tasks using Mathematica's parallel processing API's, and some processes will run more efficiently than they would on a single code, but you will need to do work to ensure that the parallel processing is well balanced across the cores. Try to ensure that you load the 64-bit version of Windows (if you are using Windows!) and that there is sufficient memory for the number of parallel processes you decide to start.
