Two ATmega328's with one crystal

Is it possible to use one crystal across two microprocessors? I am trying to cut down on component count on my current project which requires two microprocessors, for speed. The one is interfacing with 3 DACs and the other will be handling RF communications. I need these to be as fast as possible that is why I am separating the two functions onto different chips. I am achieving close to 400 Hz on the main DAC chip.

So, can I splice my oscillator signal?

PS - I am an electronics newbie, so sorry if this is a simple question.

look at the dual core arduino post, it'll answer your question:
