Which is better? The Powermac G5 2.3GHz dual core or the Powermac G5 2.3Ghz dual processor? I think the dual processor is better because it takes full advantage of the bus speed.
Got a tip for us?

Probably because it's just a slighter newer computer with slightly updated components, I don't know the exact specs off the top of my head though.
cos its 512kb cache vs 1mb cashe in the 2.3DC.. thats why.. 
Ive owned both boxes.
actually amazed the difference isnt bigger...

No. That's wrong.
It's the dual core. Smaller manufacturing process for the procs (meaning slightly faster processing because it doesn't have to use the bus to move between cores, among other things), PCIe bus slots, 2x Gig-E, cheaper DDR2 RAM, and it uses an easier to find APX/BT card.
In terms of real world performance, the difference is probably negligible, but there you have it as to which is "better."
1 MB L2 vs. 512 KB L2
8.5 GB/s memory subsystem vs. 6.4 GB/s
Somewhat improved memory controller (still high latency though..)
Zero time to talk in between the two CPUs, as they're on the same die.
Makes up for only a single bus, vs. having two for each CPU (which was probably overkill anyway, given the much lower memory bandwidth vs. bus speed).
