Will I notice a difference

[Monkey Puzzle]

Hi, I'm in the process of speccing a new machine - I'm planning on getting a Gigabyte DS3R is it worth getting a sound blaster audigy 7.1sehttp://www.overclockers.co.uk/showproduct.php?prodid=SC-040-CL&groupid=701&catid=11&subcat=?
Will I notice a significant difference? Finally would it be worth it - I'm trying to make as cheap a machine as possible...
