My uncle has a set of 5.1 speakers (Creative Inspire 5100), but he doesn't have a soundcard to support it. So he told me to go get a soundcard that supports these channels. Now, he gave me a budget just enough to buy a SB Live or an Audigy LS. There's almost no difference in price between them here. Considering the Audigy LS is running EAX 3.0 in software mode, that'll have some load on my cpu, which is only a 2.0GHz. For current FPS games, I know I need spare as much cpu power as I can. However, if the cpu load the soundcard causes is only trivial, then I might think otherwise. So please help me decide on this one. Please consider the best match with the speakers and the cpu, etc.. Thank you very much.
