I want to get a creative labs z sound card but I also want a headset called CM Storm Sirus - Gaming Headset with True 5.1 Surround Sound and Control Module to use with it...I can barely find any 5.1 computer speakers but if i use the logitech ones how to hook it all up? Do i need a switch of some kind that works between the headset and the speakers or a splitter to use them at the same time...Any wisdom you share is a great help in this issue...
