I just happened to see this and wondered if there would really be any value to us:
"Where the X5 really shines is in conjunction with the SD6128 stepper drivers. These drivers are capable of 1/128th microstepping, which is 4 times more than the the stock SD5984 drivers the board comes with (1/32) and probably 8 times more than what you are used to (1/16)."

Microstepping is nice and it will probably make your printer slightly quieter, but the sd5984 drivers are already very quiet compared to both the a4988 and drv8825 drivers so it may not be as big of an improvement as you'd expect. As for stepper accuracy and power, I'm not sure how they would compare!
