I was wondering if anybody has an AMD K6 3D processor, and what kind of sound card works well with them? I looked into the Lexicon Core 2 and it won't work with the AMD K6. I am also waiting on feedback from ECHO because I hear there may be problems with the ECHO Darla and the AMD K6. I am looking to spend no more than 300 - 400 bucks. Any answers or insight will be greatly appreciated.
