hey guys i'm planning to buy the altec lansing vs4241 in a day or two .. i've got a p6t deluxe, will the onboard be good enough or should i buy a card? was considering the xonar dx but i'm just not confident about drivers! not an audiophile and infact this will be my first good quality speakers .. lol .. used cheap 2.0 speakers for a long time! using creative sbs 200-something speakers
