Sound Card upgrade for USB Headset useless?

[Chowganhime]

Hello all,
I'm not sure if this question has been posed recently but here it is. I am planning on upgrading my systems audio components from the current on-board audio I am using, I was looking at different sound cards and headphones but wondered if having a high quality sound card affects a USB headphones performance at all. I would imagine that it would not have a large impact if any at all considering the sound is now being processed via USB and not the audio jacks. Just some clarification on this would be great. Thanks in advance.

I would imagine that good quality headphones would benefit from a USB connection...

Well I would expect so, but my question is whether or not a sound card will further increase the quality ...

The total quality of your entire computer and the addition of a good quility sound card would determin the sound from the headphones
