That file on Highend3D is not necessarily representative of Maya performance. I've done a wider range of benchmarks and the results are dramatically different on the G5 depending on what you're doing:

Here's my CGTalk thread about it. I've provided links to the test files as well.

Bottom line is that for Mental Ray renders and wrap deformers the dual 2 GHz Mac does quite well, but it lags in some other areas.

This tells me that a G5 optimized Maya could be a huge improvement.
