Hi,

I need to select one of the following computers, could you recommend
which one is the best, I just list /proc/cpuinfo and /proc/meminfo as
the rest are roughly same and I do not care that much.

Thanks a lot.


PC1: This is 4-core PC, I just list core 1 as the other 3 are
identical. Personally I think this is best, but I am not sure how to
take advantage 4 cores.

The first CPU is a Dual Core not four core, but it is the
fastest of the three. All of these are older CPUs.
