Thanks for the links.
I guess that I am trying to determine whether an 8 core is really worth it
in terms of performance now and in the future.
I read some reports that discuss that there is a memory bandwidth bottleneck
for the 8 core given the rest of the specs of the system and so it might not
be a useful choice over the 4 core. The whole system would need to be
developed further, maybe with faster memory speeds beyond 667, and perhaps
some architecture would need refinements to ever get the real benefits of 8
core, regardless of whether the software is being optimized for multicore
systems.
If this is the case, then maybe 8 cores are a good idea that needs the next
generation of refinements for the rest of the components to catch up to its
potential.
I don't really know the stuff well enough to form a competent opinion, so I
keep reading as much as I can before making a buying decision.
My choices now are whether to stick with a 4 core and improve the ram and
fast drives and video card or go with 8 core in the hopes that it already
has adequate support from the rest of the system architecture so that when
software is optimized for it it can really deliver its full potential. You
can always improve the ram and drives and video cards but you are basically
stuck with the processors and underlying architecture until they redesign
the computer itself.
On a separate question, if you want to also run windows, is it better to
install the 64 bit version so that it can access the full amount of ram in
the system rather than the 32 bit version or does this not apply to a
windows installation on the Mac Pro?
Thanks for any advice.
