Watch my specs below...

I could operate my MOTU down to 64 buffer 96KHz-that's nearly 0 latency- without a glitch if i turn graphic card acceleration off but i leave it to 256 buffer just to be safe...Latency there it's about 2ms which is pretty good IMO.
If you want latency free playing you have to get below 5ms and if you use Ableton Live just hit that "LIVE" button.
