Mac / Photoshop Performance

I've been doing some more computer research as of late.  Trying to figure out how to best speed up my photoshop workflow.  So yesterday I wrote Rob-Art over at Bare-Feats to ask a mac question and he answered well and also pointed me to an online guide I think might be useful to some of you.  Fascinating stuff.
