You´ll not here much of a difference if you run your X-Fi card without any settings turned on. Turn on CMSS (I think it´s called that) if you have atleast 4 speakers and also 24-bit crystalizer. It sounds so much better and yes if you have good speakers you don´t have to change the EQ...
I myself have Soundblaster X-Fi Elite Pro and it sounds so much better than my old Audigy 2. The Audigy card didn´t get the sound so nice like the X-Fi can...
