I'm buying my first pair of headphones. It's primarily for using while sitting at my desk working, so I'll be using them with my computer.

Q#1: Do I really need a headphone amp, or is straight off the motherboard (or soundcard) ok?

Q#1b: If so, what do you recommend, knowing that this will essentially be soley for at my desk with my computer?

fyi...getting the audio-technica ATH-A900X headphones.
