I am currently using a standard soundblaster pci card suplied with my dell 4100 system. I use some creative surround sound speakers and the standard pc speakers suplied with the system. In order for me to plug these to sets of speakers into my computer i need to use a spliter which reduces the sound quality a bit. Do you think its worth me purchasing a new sound card to make use of the surround sound capabilities of my cambridge speakers along the standard ones without the need for splitter?
