Considering each core is quite a bit less complex than a G5 (and they share a cache) I'd say it's reasonable to assume each core performs worse than a G5 of the same speed. And games are primarily (right now anyhow) concerned with integer performance, an area that the G5 was weak in, so the 360 cpu should be even weaker. Not to mention that the 360 cpu is an in order cpu, and if you compare the performance differential between an x86 in-order and OOE cpu, the performance of the OOE cpu can be 2x to 3x greater at the same mhz.
As far as the graphics processor, it was a custom job, but it still shares a lot in common with the x1800, though its feature set is a bit more progessive and it has some additions that make sense in the console space but not in the PC space. (all at the expense of raw performance though, it's not like ATI is magically able to put more advanced silicon in less space than their pc parts)
