Sound-card duel : Xonar DX vs X-Fi

Hi,

will keep it short :

1. Budget - ~4k

2. Need - gaming as well as movies-music

3. Config - Asus Z68 V-Pro; Corsair TX850 V2; MSI GTX580 Lightning; Logitech 2.1 spkrs

till now, read xonar DX better over simple x-fi...better drivers, crisp sound. any other card in this price range ? getting xonar DX for an offer-price of 3.7k. plan to upgrade spkrs a little later.

pls suggest...will add on to the post if reqd.

thanks !

anyone ?!
