Just out of curiosity, for various tasks, what would you say are the mininum ram requirements on powerpc? For me personally I find usability of Leopard to start around 1 gb of ram, maybe slightly less. 2 GB is when it feels properly responsive. I got what I think to be a decent deal (6 1gb sticks for $20) for my G5 awhile back and I've been thinking about it recently. I don't think I REALLY needed the extra ram beyond the 4 gb I had, but being at 8 is a good feeling. But this machine just doesn't hiccup now. For whatever reason it feels super responsive. I'd like to be able to justify that ram amount with the fact that I have projects easily exceeding 30+ tracks in music but sometimes I wonder. Although I want to start using Blender and Final Cut Pro and it will sure help there. I think with Leopard 1 GB is the min and 2 GB is preferred, as well as the fact that anything above 4 seems to be pushing it as the ram at the point seems to be diminishing returns. But in my case it was a "why not" price. I'm just curious about other peoples "ram guidelines" if you will.
