Every G5 graphics card is Core-Image capable and so they'll all run 10.4/10.5 "fine". Terra Soft Solutions' focus on Apple hardware and generally fewer. Graphics, I'd say only to bother with if yours is failing or you need something like dual-link DVI to run a 27-inch 1440p display. It can't hurt to put a bit more RAM in it, although it's probably not worth actually maxing the RAM, 64-bit graphical software didn't really come to the Mac until much, much later and so to max out, especially the later/faster G5s is almost entirely performative or because you want to keep several disparate task sets in memory.


At absolute minimum this machine is sixteen years old, and you can not think about or treat it as if it were a modern computer or as if there is any hope at all that you'll be able to do modern things on it. In addition, games aren't like word-processing packages that people keep upgrading. You've probably already discovered it, but just in case, as a heads up, this is not, by any means, a modern computer.
