With P-5.1, I didn't see any render-speed change going to
256 or 384-megs of RAM - just better stability at 256
with some unrendered audio filters in playback. BTW, I was
going to go to 512-megs to try out the advice of "AI" that
this would improve render speed, but found that my MB maxes
out at 384, darn... Going from 450MHz to 800 MHz did
improve render speed by 1.5, but at the time it cost me more in
time and money than that was worth - but now, with "cheap"
800MHz P-IIIs, that could be a worthwhile upgrade. I
tried P-6 briefly on another computer, and it was a
disaster (like 5.0 when it came out), so I will wait until
things stabilize with it more - I prefer stability to
using the "latest thing".;-) When P-6 is reliable, I will
then see if various HW upgrades are worthwhile to me
with that. (Dual CPUs with P-6, anyone...? ;-).
