A computer with a dual-core processor (one processor with two cores) and a computer with a dual processor (two separate physical processors) will perform largely the same. However, there are some differences. For example, a computer with a dual-core processor puts a lot more stress on the processor. Depending on what you are using your computer for, you may want to know whether you have a dual-core processor or a dual processor. This is relatively easy to find out.
