The K is overclockable and the S is not.
what is the advantage of overclocking?
The advantages are that you will be able to get more processing power out of your CPU. This will increase FPS while gaming as the processor can now handle more compared to when it wasn't OC'ed.
Be aware of the fact that you can't really OC the 3570k without an aftermarket cooler as the temperatures will get too high.
