Default Sound cards real bandwidth

Hi!

I'm working on a project in which I send analog signals from PC (LabView) at
frequency of (0-60)KHz.
I wonder if there is a possibility to send such signal via soundcard... I
found that some models with 192kHZ C/A have wider bandwidth than 22KHz. For
example:

Sound Blaster X-Fi:
Audio Output:
Response bandwidth (10-88000)Hz

M Audio Audiophile 192:
Audio Output
in some specs response bandwidth (20-80000)Hz
in manufacturer specs bandwidth +/-0.1dB, 20Hz to 20kHz but at 48kHz
sampling rate

But is that for real?

The best solution will be to test these soundcards, but I don't have such a
possibility, so if someone knows something in this matter I'll be grateful

Cheers, Martin
