A DAC converts digital audio (i.e. sound data) into analog audio (i.e. a 'sound wave')
The output of a DAC is very low-power, so after the DAC you need an amplifier, which then plugs into the headphones.
Computer > DAC > amp > headphones
Your computer motherboard already has a DAC and an amp built in, which supply your motherboard's headphone socket.
The onboard audio jack is analog already, so you can't connect a DAC to that.
The Fiio E5 is an amplifier, not a DAC.
The amplifier has more of an effect on sound than the DAC does, and the headphones have the most effect on sound.
You will never notice a 'huge' improvement with a DAC unless your current one is broken, especially with the ATH-M50. If you want a huge improvement, look at this thread: http://www.head-fi.org/t/413900/how-to-equalize-your-headphones-a-tutorial
