[MacDV] Planning a Dual G5 purchase for video use

[Brett Conlon]

Hi Richard,

Exactly!

I believe that 512MB RAM is enought to keep OSX and maybe one or two basic 
apps open before it begins paging out memory to the Swap file/s on the 
hard drive. The more apps you open or the heavier processing you do (eg. 
graphics or video work) the more virtual memory usage and page-ins and 
outs that have to take place which dramatically slows down processing.

I believe 1GB is really the starting place for any reasonable OSX Machine. 
Everything above is an enhancement.

Hi Timothy
As Brett says maxing the ram does make a huge difference.
But its not just the applications that are speeded up; OSX loves ram. 
Its memory management is very effective in allowing you to do heaps of 
multi tasking.
This means you can keep your apps open and have instant access to them 
and allows huge improvements in productivity, simply by not having to 
shut them down and start them up.
I have a Dual 2gig G5 which had only 512megs of ram at purchase, I was 
disappointed in the perceived speed change from my G4 867. But when I 
put in another 1.5gig of ram the change was dramatic everywhere, the 
only thing that really has not changed to keep up is the brain 
operating the keyboard, oh well, our Steve hasnt worked out that one 
yet.
Kind regards,
Richard Dalziel-Sharpe
