I recently put money down on this set of speakers for listening, and it struck me that I was still using on-board audio. I'm not a musician in any sense of the word, but I would like to put at least some money towards having a better listening experience for the remixes here and just in general on my desktop computer. I did visit the sound card thread that was geared more towards people producing music, and I did some searching around on my own... the card I'm looking at as a result of that is the ASUS Xonar DX. I am running Win7 64-bit, and I am somewhat nervous about compatibility, but I've read at least one review that the aforementioned card runs on XP 64-bit. Could I get some pointers or suggestions? Am I at least looking in the right direction here?
