I'm on a low budget ($130 or so)...and I was wondering if a sb audigy (oem) and logitech z540 speakers are good for a low budget sound system...I don't really care how loud it goes...mainly because I don't really need something that'll knock the pictures off the wall and I'm sure the volume will be enough for what I'm looking for...95% will be games and 5% will be playing my limited number of mp3's...anyone have suggestions?
