Would 10.5 improve the speed of my Mac or slow me down?
It'll slow you down about 20%. It's the same on all PPC Macs running
10.5. I personally believe it's some type of planned obsolescence by
Apple, after all, Leopard 10.5 made Intel Macs faster, while making
PPC Macs slower. The same goes for iOS on the iPhones, iOS 4 makes
iPhone 3's & 3g's slower, but makes iPhone 4's faster. There must be
some way they manipulate the OS to run slower on old hardware.
If you look in the XBench archives for dual-500 Gigabit, you'll see
that the highest scores were all with Tiger 10.4 at about 30,
(absolute high 30.97 by taka2), while best Leopard 10.5 score is 23.98
by G4DP500, so it's more than 20% slower for Leopard. I'd stick with
Tiger.
