I installed 10.5 on a 550Mhz G4 Powerbook with 768Mb of RAM. It runs OK, but 
there are some hang-ups, and you can't open a lot of apps at the same time. 
My advice:
1. Max out the RAM.
2. Get a better graphics card.
3. Optimize 10.5 by turning of the glass dock, and disabling Dashboard. If you 
do some research I think there are some other features you can turn off that 
will help performance.
