I don't know about the two systems you mentioned, I barely know that creative blaster system. But I'm sure you'll like it.
The creative sound blaster is 10 years old on the z97 motherboard, and to me it's better than the current Realtek one, it has more features + the wonderful scout mode.
But I'm sure other companies are doing similar features for gaming sound clarity.
Yep, there's one on amazon for $40, but I don't know if it supports this feature or not.
