PWM Frequency

Hey guys. Just got my arduino last night so I just started working on my project today. I was testing the PWM and i get 490Hz. I only need about 1% resolution on it so by just using the digital output pins I can create a PWM to run around 2.3kHz. Is there a way to speed up the PWM output? Speeding up the PWM pin instead of making my own PWM function with a digital pin would make my life much much easier. Thanks guys.
