You can use RightMark Audio Benchmark tool for testing Soundcards.

Here's my RightMark AA report

Realtek ALC850 Audio on ASUS K8N -

Testing chain: External loopback (line-out - line-in)
Sampling mode: 16-bit, 48 kHz

Summary

Frequency response (from 40 Hz to 15 kHz), dB: +0.21, -1.21 Average
Noise level, dB (A): -78.4 Average
Dynamic range, dB (A): 77.5 Average
THD, %: 0.057 Average
IMD, %: 0.071 Good
Stereo crosstalk, dB: -78.5 Very good
IMD at 10 kHz, %: 0.111 Average

General performance: Average


Here's how I tested -

Select option "adjust playback recording levels"
Connect Line out to Line in with a stereo cable.
Hit button "run tests in loopback mode"
Save results to html.

Any more volunteers. It'll be good to see how different onboard audio codecs and high end soundcards compare.

PS EDIT :
Compare my result with Creamware Scope DP soundcard http://audio.rightmark.org/test/creamware/scope44.htm
