Depends on what you want to do... As long as the latency is *constant* 
(as in, no granularity for MIDI events), a few ms more or less is no 
big deal. Use headphones instead of near field monitors, and you cut 
some 3 ms right there...!

If you're trying to route the monitor sound for a vocalist through the 
computer, latency might be more critical. It feels pretty weird if 
the monitor sound is significantly delayed, but I'm not sure exactly 
how much one can tolerate.
