Leopard with Powerbook

Have you considered searching? This gets asked over and over. The answer is YES, although some older PPC machines may not be supported (i.e. the oldest machines Tiger supports may not be supported in Leopard, this is normal).

 

Not "a version" of 10.5, it is 10.5, there will only be one box.

Leopard is Apple's first Universal Operating System designed to work on both PowerPC and Intel processors. Leopard will run with identical features and abilities (aside from Boot Camp of course) on Macs with PowerPC or Intel processors.

So long as your graphics card is up to the job of displaying all the Core Image goodies (most aluminium PowerBooks are - I presume yours is an AlBook, please tell us what you have) then you will see Leopard with all the cool eye candy as well.
