What does a dual core processor actually do in real life terms?

In regards to actually sitting down and using a computer, what differences are noticeable when using a dual core processor as opposed to a single core? Some examples would be teriffic. Thanks

there are 2 processors. If the O/S (operating system) can utilize the other core (processor), then it can use the 2nd core, for example, to run another application instead of giving the 2nd application time slices. The result is that you see greater speed (shorter job time) for 2 apps running concurrently. That's enjoyable for the user...more work getting done faster.

But it's arguable for the gamer. The gamer generally runs one application (game) at a time. And many games are not yet written to utilize the dual core. That means you might get better performance from a single core than a dual core, or that you might see no improvement in speed over the single core. In fact, you could see a performance hit with dual core.

There are some great performance charts for games and other apps across a wide variety of CPUs on Tom's hardware...link below. Note that Wolfenstein (an old game) does better on a high-end single core CPU than many dual core. It wasn't written with dual core capability.
