I would not be too interested in seeing PPC970 (900Mhz front side bus) on a motherboard with 133Mhz memory bus...  

If the CPU card would be build with some 900Mhz onboard memory, then the performance would be decent, but then the price of such a CPU card would be around new PowerMac...

Better just design a completely new motherboard ... in 2005 or so....

"If anything it will run 32bit software slower than a comparable 32bit processor."

That might be true with some of the 64 bit variants of future x86 CPUs where there might be no full backwards compatibility. But PowerPC has been designed to be 64bit in the very beginning, so I would not expect any slowdowns with 32bit code.

( Hyperion guys at OS4 list about 64bit PPC.
"64 bit PowerPC architectures *can* run their 32 bit subset code with no
speed penality (as opposed to IA-64), and only marginal changes in the
OS code and no changes in user code needs to be done to achieve this.")
