What are the benefits of multiple cpu core computers?

What are the benefits of a computer with dual cpu cores over a single cpu core computer? The fastest dual core computers i can find to buy are 2.4ghz, but single core is around 3.0ghz.

Wouldn't that make it slower then a single core? I'm curious because i want to get a new computer and am looking at the differences between the two

Its funny how people say dual core is the addition of the 2 cores in the cpu. For example, if a dual core cpu has a clockspeed of 2.8ghz, it is NOT 5.6ghz!!! In reality, they actually dont add up.

dual core is usually faster and gives better performance.

WHY? because there is 2 physicall processing cores.

For example, if you run a game, it might be taking a whole cpu core! But... dont worry, we have 1 core left in a dual core CPU. you have more opportunity to run more programs and use the 2nd unused processing core!

On top of what everybody else suggested, we may able to crack a 6 digit password thank to the processing power.
Think of it this way, if you have a rocket with one engine you will go fast, but with two you go at faster speeds and most stable.

lol kind of a funny way to think of it. :)
A single core running 3 GHz outruns a dual core running 2.4 GHz, IF there is only one thing going on at a time. If there are any parallel operations, the 2.4 GHz is more competitive and may outperform the 3 GHz single CPU system. For example, on my dual core lap-top I have 82 processes and 852 threads active, while running FireFox (and all kinds of background stuff - firewalls, virus scanners, backup software, who knows what all). My system usually runs faster than a single CPU box with a 20% faster CPU, but not always. In particular, my single CPU desktop is prone to freezing for 2 or 3 seconds before responding, the multiple core CPU boxes seem to do that much less often.
