Sound Card vs Onboard Sound?

[Deathz]

Hi all,
I just wanted some opinions regarding a dedicated Sound card vs Onboard sound.

If one JUST uses headphones for gaming, listenening to music is there any point in getting a dedicated sound card compared to the ones built into the
X58 motherboards?

I currently have a SOUND BLASTER X-FI XTREME, would the onboard be similar?

Lastly, does a dedicated sound card really improve fps in games these days?

I dont use any speakers, just headphones.

From what i can make out its a Creative sound blaster X-fi, cant find the specifics but it seems to be an oldish card. (sorry if it doesn't help)

Thanks for all the feedback guys.

what headphones have you got mate ? and are you into serious music listening ?

Just some cheap £10 sony/panasonic headphones.

But ive decided i'll get a soundcard for music/games. Is the
Sound Blaster® X-Fi™ Xtreme Audio any decent with a windows 7 64bit setup?
Or should i splash out for the Sound Blaster® X-Fi™ Xtreme Gamer?

Thanks
