To keep it plain and simple: Up until now I've used mediocre headset with onboard audio, recently acquired some cash and with that I'm giving my computer a good audio upgrade. I'm getting the Sennheiser G4ME ZERO for my headset but concerning the sound card I felt a bit conflicted. D1: $75 but probably not as good D2: $165 but probably better Which should I get? Is the D2 well worth the extra money? Or is the difference only marginal and I should go with the D1 and save myself some money?
