it does. standart onboard and so on cards usually have ok output
something that would go for the most users of the world because not everybody are audiophiles.
second thing about sound cards is that most of them produced for out put purpeses the input usually crap, low sensitivity low spectrum low what ever and how ever you want to call it that causes shity sound results.
now days i am using onboard sound card for gaming and movies its some stock7.1 crap
though for recording and sound work i am using ESI Juli@

new neck or fretboard wont ruin your guitar its just that i doubt you will manage to sit it in the correct spot.
i am not sure how you are going to strip the fretboard off your neck and glue a new one but if your skills are good enough good luck.
don't forget to show us the results of your work.
the other thing is that even if you do find a replacement neck with the same holes where neck and body joins, most likely your intonation of the entire fretboard will be incorrect.
the thing in guitar is no matter what scale length you choose its the way the length is divided.
the 12th fret is always in the middle between nut and the bridge
the 24th fret is always in the middle between the 12th fret and the bridge
so what you would have to do is to make sure your new neck will sit in the correct spot to preserve this rules. elsewise you can forget it intonation being correct.
other thing you can do is to continue the fret board on your body the upper frets will be harder to access. i have never saw nor heard any one doing so so you might be the first one. and again provide with some pics when you done.
and the last thing do your research on this website i gave you before and google it up some more info about it and you will know how much it is possible or not possible.
EVERYTHING is possible the only question is are YOU able to do it or not.
and then i have to wait a while for more $$ to get a cab
