Presumably, the G5 is currently fast enough that it does pretty well
with just L1 and L2 caches. It's certainly possible that some time down
the road they may add an L3 cache to the mix.

memory protection. You'll never see VM go bye-bye then unless you give
up memory protection. However, the 8GB means things will be far less
likely to swap to disk -- so you'll have all the virtual memory in real
RAM instead of some in real RAM and some on disk.

high. What other equipment are you putting on this thing? If I recall
correctly, the base price for a dual 2GHz is $3000.

still get a good speed boost. However, they will need to be modified to
take full advantage of the 64-bit features and other niceties of the
chip. Hopefully all that will be necessary to accomplish this will be a
recompile (assumign the programs were well-written to begin with and
didn't make any assumptions over whether quantities are 32-bit or
