The future for Intel appears to be a
re-engineering of their power consumption
across the product line, with greater
emphasis on work/watt and less emphasis
on raw clock speed. Thus, look for their
dual-core CPUs to shrink in size again, and
to emerge much cooler and scoring higher
in work/watt, e.g. by leveraging the
superb engineering that produced the
Pentium M (see THG's article on the
37 Watt system).
This switch was motivated by a realization
that dual-core Prescotts could not be clocked
above 3.4GHz without generating excess heat.
Thus, the 840 has 2 x 3.2GHz Prescott cores
for now. Be prepared to address overall
cooling and ventilation in your case,
if you choose this route now.
For a good PCI-Express motherboard,
we highly recommend the ASUS P5WD2-Premium,
going for about $200 wholesale. It runs
all current Intel CPUs.
If you don't need any of the benefits of PCI-Express,
then the ASUS P4C800-E Deluxe with 875 chipset
is still available (~$170): look for the 3.4GHz
Northwood core (512K L2 cache) because it
runs faster and cooler than a comparable
Prescott core. These Northwoods are a
vanishing breed, however, because Intel
has migrated to the Land Grid Array (LGA)
instead of the Pin Grid Array (PGA).
