The OS drives it though.

Not only that, but MIDI is also 8 bit. :o) But really anything that has to do 
with data transfer can be done twice as fast as long as the corresponding bus 
and chip is 64-bit as well. And datatransfer between chips is really the main 
limiting factor on the speed of a computer in general.

Yep, and more precision means less range loss on signals that pass through 
effects softly. And better summing (oh dear, I said the s-word) ;o)
