4.7 Our Picks

Although
processor makers probably hate us for saying so, the processor
actually plays a relatively minor role in overall system performance.
The difference in absolute processor performance between a $50
processor and a $500 processor may be a factor of two or less. Nor
does buying a $500 processor make your system run twice as fast
because processor speed is only one element of system performance.
Before you plunk down $500 for a processor, consider instead spending
that extra money on more memory, a faster video card, a SCSI hard
drive, or all of those.

AMD Athlon XP . In this price range,
spend $75 or so on the processor. We recommend choosing the
least-expensive Athlon XP you can find in retail-boxed form. Low-end
Athlon processors provide incredible bang for the-buck. Your system
won't be quite as fast as one that uses a midrange
or faster Athlon XP or Pentium 4, but it won't be
all that much slower, either.

Be very careful when buying inexpensive processors. A price much lower than $75 may mean that you're being quoted on discontinued inventory. That's fine if you know what you're getting and are willing to accept the older processor. A lowball price may also mean you're being quoted on an OEM version, which does not include the heatsink and fan, and may have only a short guarantee rather than the three-year guarantee on the retail-boxed model. By the time you buy a separate heatsink and fan, you'll probably spend more than you would have by buying the retail-boxed model in the first place. Caveat emptor definitely applies when you buy any processor. Ask specifically what you're getting or you may get a nasty surprise.

Intel Pentium 4 or AMD Athlon XP . In
this price range, you have a bit more room to play, and it makes
sense to allocate some of that extra money to a faster processor. At
the lower end of this price range, choose the fastest retail-boxed
AMD Athlon XP you can find for $100 or so (the Intel Pentium 4
doesn't compete in the $100 price range). At the
higher end, choose the fastest retail-boxed Intel Northwood-core
Pentium 4 or AMD Athlon XP you can find for $150.

Intel Pentium 4 or AMD Athlon XP .
This budget level provides considerably more options. For
a system in this price range, choose the fastest retail-boxed AMD
Athlon XP or Intel Pentium 4 (533 or 800 MHz FSB) you can find in the
sub-$200 range.

AMD Athlon MP . If you run Windows
2000/XP, Linux, or another SMP-capable operating system, we recommend
using a dual-processor system. In our experience, responsiveness in a
multitasking environment is better with two midrange processors than
with one fast processor. If you choose components carefully, you can
build a dual-processor Athlon system for only $250 or so more than
the cost of a comparable mainstream system. Your system
won't run any one task as fast as it would with a
faster single processor, but it won't bog down when
you're running many tasks, as the fast
single-processor system will.

TaiSol or DynaTron . A retail-boxed
processor includes a heatsink/fan unit that is perfectly adequate for
routine use. If you buy an OEM processor, which does not include a
heatsink/fan unit, or if you overclock or otherwise push your system
beyond its design limits, you'll need a high-quality
third-party heatsink/fan unit. Such units vary widely in price,
cooling efficiency, and noise level, but the best units overall in
our opinion are those manufactured by TaiSol and DynaTron. We have
used various TaiSol and DynaTron heatsink/fan models on various
processorsincluding Celerons, Pentium IIIs, Pentium 4s,
Athlons, and Durons running at various speedsand have found
them to be effective, quiet, and reasonably priced.

We constantly test and review processors. For information about which
