When asking questions comparing your onboard sound to an add-in sound card, please be aware that AC97 is a standard interface for converting digital sound signals into analogue sound fed into the ports on the back of your motherboard. Saying you have AC97 onboard sound is the same as saying you have a PCI sound card: it doesn't mean anything.
When asking if your onboard is good or not, we need the actual name of the sound chip.
