getting a new computer

I don't much care for the dual AMD, it takes extra cycles
when the two procs
need access to the same ram. The OS is going to address the
RAM the same way
regardless of which proc is using it, so if you are running
a multi-threaded
app that uses both CPUs they will be doing a lot of extra
talking on the ram
controller. In a single socket system I think it is great,
just not in the
multi-socket world.

The Dual core stuff works out to about 1.7 procs from a
performance
standpoint, but in general CPU has not been a bottleneck in
years. The
problem is either going to be the Disk IO or the memory.

In the new Intel stuff the ram is on the same bus with
everything else. No
more North/South bridge stuff.
