hi i was wondering if anyone here uses the soundblaster extigy. i am thinking about getting one and wanted to know your opinions on it. originally i wanted audigy platinum, but i dont have an open expansion bay:(

also i was wondering exactly how the digital in works. if i hook up my ps2 with an optical cable to that and provide with appropriate speakers (like creative inspire 5300) will i get 5.1 sound or what will happen? thanks a lot!
