Depends on how many active channels, the algo used in the software EC, how the 
driver's compiled (optimizations)...  it's not a simple answer.  You need to 
benchmark it yourself.

My short answer is: If you're not running into CPU issues, don't worry about 
the hardware EC.  You're not saving anything.  When you start having trouble 
with CPU usage, look at getting the module and adding it in.
