protools and an extra audio card on the same comp

[DHG MUSIC]

Hello gentlemen, Does anyone know if it would be possible for me to try this set up


G5 dual 2 ghz processor

I have protools 7.1 with 6 hd accell cards

Can i Install logic on the same computer ans use a focusrite saffire as the audio card at the same time that protools is open?
I dont want to use tdm, its way to buggy, but I have the option to install logic in another g4 or use it on the same computer

The main reason I want to have Logic on th g5 its because i have the apple 30inches display and I love working on that


Please any advice would be greatly appreciated
