I am using this sound card for my laptop and I have no issues with transfer rate. If your not experiencing any right now, I would suggest this move could degrade your audio quality as you are now adding another 3.5mm audio cable to move the sound. Personally, I have had occasional issues with 3.5mm jack connections adding noise. If it were me, I would disable the internal sound card and just use X-fi with basic drivers if you need the outputs this card offers. Avoid installing the soundblaster "bloatware" if at all possible.
