Greetings,
I am acquiring a new computer in order to conduct data analysis. I
currently have a 32-bit Vista OS with 3G of RAM and I consistently
run into
memory allocation problems. I will likely be required to run
Windows 7 on
the new system, but have flexibility as far as hardware goes. Can
people
recommend the best hardware to minimize memory allocation problems?
I am
leaning towards dual core on a 64-bit system with 8G of RAM. Given
the
Windows constraint, is there anything I am missing here?
Perhaps the fact that the stable CRAN version of R for (any) Windows
is 32-bit? It would expand your memory space somewhat but not as much
as you might naively expect.
(There was a recent announcement that an experimental version of a 64-
bit R was available (even with an installer) and there are vendors who
will supply a 64-bit Windows version for an un-announced price. The
fact that there was not as of January support for binary packages
seems to a bit of a constraint on who would be able to "step up" to
use full 64 bit R capabilities on Win64. I'm guessing from the your
failure to mention potential software constraints that you are not
among that more capable group, as I am also not.)

I know that Windows limits the RAM that a single application can
access.
Does this fact over-ride many hardware considerations? Any way
around this?
Thanks,
JD
