The clock speed doesn't matter. What matters is how fast it runs programs.

Think of the clock speed of a processor as being like how many steps
per minute an animal makes. Even though a centipede makes many
more steps per minute than a race horse, you know that the race horse
can move much further than the centipede in a certain amount of time.
Why? It is because the horse makes so much more progress with each
step than the centipede. AMD processors also make a tremendous
amount of progress per clock cycle.
An important thing to remember is that the review of the Athlon 64
I posted a link to is for use of the Athlon 64 with a 32 bit operating
system(Windows XP) and 32 bit software. One should expect
even greater performance running 32 bit software using a 64 bit
OS(it can run 64 bit software side by side with 32 bit software when
a 64 bit OS is used), and even better performance running 64 bit
software with a 64 bit OS. The typical Pentium 4 chip is a 32 bit
chip.

Go for the Athlon 64.

In many cases the Athlon 64 is much faster. This includes business software
and games. The important thing to remember is that the Athlon 64 allows
future upgrades to 64 bit software.

Buy an Athlon 64 system. Make sure to get a good video card since
you want to play games. In Doom 3 for example, a $160 Athlon 64 3000+
chip beats an $825 Pentium 4 3.2 ghz EE chip.

For Business Winstone 2004, a $190 Athlon 64 3200+ beats a
$1,000 Pentium 4 3.4 EE chip.

Another reminder. all the benchmarks I have referenced were for 32 bit
software using a 32 bit OS. The Athlon 64 can run 64 bit software when
a 64 bit OS is used.
Here is one example using 64 bit software(with the beta edition of Windows 64
bit) compared to the 32 bit version running on an Athlon 64. The 64 bit version
finished the task in 25% less time.

Other applications might have a much larger performance boost when moved to 64
bit. Keep in mind that the 64 bit results are in comparison to the already
great 32 bit results for the Athlon 64.
