Really? how much does it improve? like will i notice a change?

Depends, you probably won't see much of a difference in terms of CPU % used on a modern 1.7ghz+ computer, but buy moving the load off of the main cpu your going to see other benifits.
For instance when your computer is under heavy load your not going to see any reduction in performance or increase in sound latency.
It also depends heavily on the actual onboard sound and what type of sound proccessing. I would expect that stuff like the NForce2's onboard sound is going to use a healthy chunk of cpu, because much of they higher-level proccesssing it does.
For instance your going to see a dramitic difference between simply having 2 channel stereo out while playing MP3's vs having 7.1 digitally enhanced and proccessed channels blah blah blah is going to show quite a bit of difference(relatively)
I am guessing that maybe with nforce2 onboard sound going full out may use 5-8% of the cpu time, while the audigy may use 1.5-3% of the cpu time. On a slow computer you may see as much as 10%-15% cpu usage with stuff like ac97 pass-through, but then again how many people with nforce2 boards use low-end cpus?
