well ive finally decided to upgrade from my onboard sound and i have narrowed down the choices but cant decide what to do. i currently have a set of 2.1 altec lansing speakers (VS4121) but am also looking to upgrade to a set of 5.1 speakers.. but not quite sure if im willing to spend the money to get the logitech z5500s... maybe the z5500e's or the x-530s. i listen to music the most... followed by gaming, and then watch movies. i was leaning towards the x-fi xtreme music.. theres a 20 dollar rebate on ncix.com right now so i can get it for 88 dollars canadian! but i also came across the auzentech x-plosion http://www.ncix.com/products/index.php?sku=17753&vpn=BGI-HDAXP-D&manufacture=AuzenTech which has dts connect and dolby digital live and an optical connection out which i could use to plug into my 7.1 receiver which i have for my home theatre. but the majority of the my computer is hooked up to these 2.1 speakers, soon to be 5.1 if i upgrade. i am really undecided on which card to get so some other opinions may be helpful. so what would u get?
