While I understand(and agree) that the HD/Native card has no DSP, I can tell you from experience, moving from a DIGI003 to HDN gave me a very noticeable feeling of more power. I made this move while running PT10 HD software. I literally opened the PC, stuck the HDN card in and booted the computer. Then I opened Pro Tools and it gave me a message that I needed to reboot, which I did. That rig(i7 950/12GB RAM) suddenly felt much more powerful without any other change. Things that make you go "Hmmmm"
