Is an iMac G5 OSX 10.4.11 upgrade possible? (To 10.5 or 10.6 for example)

I have an iMac someone just gave me. I wanted to play around with it, but having a G5 processor in it has seemed to hinder any fun I could have with the thing. What I want to do initially is upgrade the OS. The information on the Internet is plentiful, but confusing; especially when older post say it can't be done (2002) but newer posts say you just have to call Apple (2012/2013). The main problem with this is either:

(A) I am having issues understanding the naming correlations with the OSX versions, or (B) I understand it and actually cannot upgrade this computer (or it will cost an arm and a leg to do so).

Here's the specs:

Hardware Overview:

Machine Name: iMac G5
Machine Model: PowerMac8,1
CPU Type: PowerPC G5 (3.0)
Number Of CPUs: 1
CPU Speed: 1.8 GHz
L2 Cache (per CPU): 512 KB
Memory: 512 MB
Bus Speed: 600 MHz
Boot ROM Version: 5.2.2f2

Is it possible to upgrade an iMac OSX 10.4.11 system to the next/newer OSX versions (like 10.5)? Is it costly? Will I get anything out of upgrading? Is this iMac with a G5 processor of any real use anymore (for instance, can I even get software for it)? Useful help would be appreciated. Thanks!

    Yes, it is possible to upgrade your iMac G5 to Leopard. But to get a copy, you would have to source it from an online store, as Apple no longer produces copies of Leopard. Leopard was the last OS to run on PowerPC, and at this current point in time, the PowerPC architecture is considered to be obsolete. Whilst you can still find software with support for PowerPC, you would have a much better OS X experience on an Intel Machine.

  • All would be helpful. I need to buy a copy of Apple computers for Dummies. I'm cllue less. Do I buy an upgrade disk to Leopard or snow leopard. Or can I buy the whole version? Is it worth it? Just wanted something to surf the net with, but it says that it sees my router but every time I try to go online, it says that Safari doesnt see the server. So what do I do? Don't have the money for a new computer.

  • Target mode and clone from another. Up the memory to at least 2gigs. If your new to macs it would be useful to play around with.
