HD Native / HD Omni versus 003R

[stevedemena]

On a Mac, I currently use PT9 with a 003 Rack. I don't like the fact that when Pro Tools is using the 003 Rack other audio apps can't access the interface to play audio, like iTunes, etc.

If Pro Tools is not running and I need to play audio, even an audio file in Mail it takes time for the "Digi CoreAudio Manager" to load up and for the audio to start playing.

I have an HD Native Core PCIe card coming and I am considering ordering an HD Omni also. If I removed the 003 Rack from my system and used exclusively the HD Native and HD Omni would switching back and forth between Pro Tools and other audio apps work more seamless?

Thanks. I hope I explained this properly.
