I wouldn't worry about it. All Intel Macs should scream with Leopard. PowerPC Macs will run Leopard just fine too, though they may miss out on some Intel-hardware dependent (rumored) features.

I have a Rev. C iMac G5 - the last iMac to be released prior to the Intel Macs. It should scream with Leopard just like the Intel Macs will :D
 
LOL You're obviously still stuck in Windows World™™™.

As the OSs progress, they speed up. My G3 iMac had OS 10.1 on it originally, and it was sloooooooooow. Remember this is an 8 year old computer with a 350 MHz CPU. Still, I updated it to Tiger, and the difference was literally incomparable. Tiger was SO fast (obviously not as fast as my MacBook Pro, but still damn fast).

Leopard will scream on your MacBook. All the current Macs are incredibly powerful and OS X just keeps getting better.

you said it man! exactly the way i feel!
 
With Mac's new software quickly requires a new OS, but any computer made since 2002 (2003 for iBooks) will easily run 10.5, I would expect any Intel Mac to run Leopard noticeably faster than 10.4, though if you only have 512MB RAM you will probably struggle a bit.
 
Mine is 12" iBook G4 1.33 GHz!!

Then I'd be worried about Leopard. I have a G4 1.33 Mini w/ max RAM (1 GB) but like my Mini, I believe you only have 32 MB VRAM too... though yours might support core image (the Mini's Radeon 9200 does not)

Either way, I have enough concerns for now that my Mini isn't big enough to run Leopoard... at least at a good clip.
 
Would I be correct in saying that Leopard will run especially fast on Core 2 Duos, Xeons and G5s since Leopard will ship with a 64 bit version of everything aswell as a 32 bit one?

This site says specifically the Xeons, but I thought the G5 and Core 2 Duo was 64 bit too :confused:

Sort of, but only for the Applications that are written in 64bit.

Yeah I know what you're saying, but I just mean that the actual operating system itself should be faster when compared to the Tiger which is mainly 32 bit code I think.
 
You may be pleasantly surprised. Historically, Mac OS X gets faster with every release on the same hardware. I've heard similar stories about the Mac OS X Leopard Developer Preview. If someone has said this already... sorry :).
 
I'm more preoccupied about the G3's, because c'mon, PowerPC will be on the exit line in the following years. What better way to continue the transition to Intel than leaving one PowerPC processor with each OS X. Same thing to Classic, btw. There will be a time when Classic will no longer be a "feature" in te OS.

doubtful. Tiger already has a bit of 64bit code used since the G5s were/are 64bit chips. no noticeable gains will come until all the chips are 64bit and all the apps are coded to use the benefits of 64bit, which in my opinion, there aren't all that many.

I agree with you about Classic - in fact, I'd be willing to bet that it'll go away entirely in Leopard. As for PowerPC, sure, it's on the "exit line", so to speak. Remember how long Apple supported 68k processor Macs? (These were on the officially supported list all the way until Mac OS 8.1. Mac OS 8.5 was the first Mac OS version that wouldn't run on 68k Macs.) I would not be surprised if Mac OS 11 came about before PowerPC support was dropped entirely, given Apple's history.
