My PowerMac G4/1,25: Upgrade to Tiger or Leopard?

Hello!

I am a new Mac user. I bought an old Power Mac G4 (MDD) for some bucks a few days ago. Here are some specs:
1x 1,25GHz, 80GB ATA, 64MB ATI graka, 512MB RAM, FW 400, OS X: Panther
And it is the MDD model which was released in 2003.

Now I want to Upgrade Panther, but I don't know which OS X is the best choice for my Power Mac, Tiger or Leopard?
My Mac should have a good performance. I know, Apple officially support my PowerMac, but will it run as fast as Tiger or slower on my machine?

On google I can primarily find some reports how Leopard works on unsupported macs and on them Leo works fine, but not so fast..

greets
floweb

WIth that amount of RAM, Tiger would be your best bet. I'm not running Leopard yet, but I've heard from others that it does feel slower than Tiger. Still, you could install it officially since you exceed the minimum requirements (867 Mhz G4 is the minimum), but you'd have to REALLY bump up the RAM.

Also be aware that Leopard dropped support for Classic, even on PowerPC Macs.

I've also seen some reports that the Leopard Installer refuses to allow an installation on a G4 that meets the Apple Requirements .... something to do with the G4 having been modded up to Leo's Sys Req's but the Installer just plain refused to allow the go-ahead ... I have also seen a work-around for this too.

I tend to go along with the Tiger train_of_thought. I wouldn't suggest someone bypass Tiger and go straight to the cutting edge as personally I'm really enjoying Tiger still and have no immediate plans to cast the beast aside ... I might even go against my advice and skip to 10.6 when it comes out .... bleedin' edge, I challenge you~

i upgraded my Dual 1.25 GHz MDD from 768 MB RAM to 1792 MB prior to upgrading from Tiger to Leopard, and have had no problems with performance.

(three 512's and one 256 Mb chip - and System Profiler shows as 1.75 - wth??)

Thanks for your answers!

Well, I will rather choose Tiger. I've heard similar things that 512MB RAM are too little for Leopard. And I don't want to buy more RAM chips...

I had 512 MB of RAM on Tiger and it ran OK, but it's cutting it close. It's definitely not something I would consider for Leopard. I recommend 1 GB for Tiger and more than that for Leopard. But for general use 512 MB should be fine in Tiger (I ran with that on my iMac G5 for a good while before adding an extra 1 GB stick).

I don't see any problems with that math...

512MB times 3 = 1.5GB
256MB = 0.25GB

1.5GB + 0.25GB = 1.75GB.

Well, i was using a regular calculator: 512 x 3 = 1536 + 256= 1792 MB
