Hi,
You are asking for a personal opinion. Therefore, mine is that you will be pretty well satisified with this system. You must realize that a great sound card would be best, but the quality of these onboard sound cards is much better than just a few short years ago. Personally, I just use the onboard anymore and I have been pleased with what that offers. Only if you so choose to split hairs would it become necessary to purchase an extra card. Give it a try and if not satisified, you can always add one later. That is my opinion.
