Help. Powermac G5 2.5 Ghz Newbie., advice/tips on running pro tools LE Options

[wreckthisplace]

hey all

just wondering if anyone can help me out.
i recently just upgraded my computer from a powerbook to a nice powermac G5 dual 2.5 ghz. 1 gig ram.

i run pro tools LE 6.9.2 on Tiger.

i was wondering if anyone has any advice on tweaking my powermac and/or pro tools to make it run the best it can. i use reason quite often along side pro tools. i am also using BFD drum module for drums. I plan on trying to use BFD along with my drummers roland v-drums in the near future.

one thing i noticed that i never expected to happen with a G5 was when i opened up my last session which was a small session with BFD drums along with some reason piano it stopped playback and told me to increase buffer size. and at one point it told me to decrease it. could this be a pro tools LE and tiger issue? maybe its still not stable?

any thoughts, suggestions and advice on any of this would be much appreciated. me being a powermac newbie i could use some from some more experienced users.

thanks so much.

cheers all.
