Re: Carputer 101
For the money, there are better cards out there like Defiler said. Although there is nothing wrong with Creative.
The first step in choosing a sound card is knowing what you need it to do. BitPerfect (RedGTI knows all about this) isn't supported by all cards, as SPDIF and other similar features isn't supported on all cards. Sometimes external USB cards are favorable to internal PCI cards since they are less prone to picking up noise from the computer. There is a lot to consider when selecting a sound card.
