I have a powerbook g4 1,5Gh with 1.2 Ram (1gig and 256mb) and I can hardly load more than 2 AU instr. and 3-4 plugins in DP4.6. i was just wondering what the f''' is happening. Do I have to buy 1 more gb RAM? and if so, what would be the result? i would be able to load another 1-2 instr more?? that's all? a couple of years ago I had a p3 at 1Gh and it was 5 times faster than my powerbook? So what is all about?
