hi i have an audigy 2 zs soundcard and i was wonderin if the creative speakers would perform better with the creative soundcard or it doesnt matter? i am interested in the logitech z-5300 speakers, creative inspire t-7700, and maybe either one of the creative inspire digital 5500 or 5700 or the gd580( whichever of those 3 digi 5.1 speakers are better). I mostly do gaming and listening to music on my cpu. Im wonderin which speakers i should get the digital 5.1 speakers or the 7.1 speakers? Thanks.
