It depends on your computers power, and how many plugins and tracks are in the session etc. You can track at low buffer settings and have effects on the channel you are recording. For guitar and other instruments a buffer of 64 or 128 will most likely be fine and you will be able to keep the plugins on and not use low latency monitoring. But if you have a large session with all kinds of processing going on you may need to up your buffer to keep your session stable then when going to do an overdub switch to low latency monitoring to do it to keep the system without erroring during the recording. It's definitely a balancing act. I am very happy with my native system, but I do not track bands etc, mainly mixing and tend to record one track at a time. If you are always tracking bands etc I would go HDX. We will see how this improves on a Native system with pro tools 11 as they have made some changes as to how low buffers are used. instead of all the tracks switching to low buffer settings only the track you record on will be at the low buffer and this should really make a difference for native systems and recording.
