Just wondering if I could use SparkFun breakboard for the MCP4725 DAC 12 bits to play audio sounds?

Well yes but as it is an I2C device you won't be able to put samples out to it all that often. If you run it at 100KHz that only gives you about a 1KHz sample rate. Running it at 400KHz will up that to 4KHz so it will not sound so good.
Ah, good to know, thanks bud. 
In any event, I'm FAR from doing any sound-based stuff anyway. I was just wondering about this, as its very cheap...
