I have a laptop with an AMD Athlon X2 64 at 2.2GHz, the audio tends to do a poping noise sometimes when i have several apps open, maybe like youtube, sony vegas and facebook. I was wondering if i got an external sound card like this one from creative labs or this one from sabrent would make a difference in CPU performance, also between these two sound cards, is on really better than the other? I know Creative's a really good brand, Ive never really bought a Sabrent product, nor do I know much about the company. The one from creative costs more, and looks good too, but is it really worth the extra cash, or should I just go with the Sabrent one?
