If 
you 
are 
doing 
processor-intensive 
stuff 
AND 
the 
data 
set 
and 
the
code 
are 
small 
enough 
that 
it 
fits 
into 
whatever 
cache 
you 
have,
you 
will 
have 
much 
improved 
performance 
vs. 
not 
fitting 
in 
your
cache.

For 
typical 
"home 
office" 
applications 
you 
probably 
won't 
notice
much 
if 
any 
difference.  
you 
probably 
won't 
notice 
a 
whole 
lot 
of
difference 
between 
one 
of 
these 
and 
a 
$75 
Athlon 
X2.  

without 
knowing 
more 
about 
what 
"home 
office" 
means 
to 
you, 
I'd
suggest 
you 
spend 
the 
difference 
in 
price 
on 
more 
system 
memory 
rather
than 
a 
better 
CPU.

I'm

CPU's.  
It 
seems 
that 
Intel 
offers 
CPU's 
with 
more 
L2 
cache.  
And 
the 
Q6600 
is 
a 
good 
example 
and 
runs 
about 
$250 
OEM 
+/- 
where 
the 
AMD 
Phenom 
starts 
at 
199.00.  
Both 
have 
128k 
L1 
cache, 
but 
the 
Intel 
Q6700  
has 
4M 
L2 
Cache 
in 
addition 
to 
128k 
L1 
But 
is 
a 
wopping 
$539.00

E6600 
and 
E6400

chips 
and 
am 
very 
happy 
with 
them.  
The 
E6600 
runs 
Open 
Suse 
10.3 
and 
the 
E6400 
runs 
Windows 
XP 
(yes, 
there 
are 
a 
hand 
full 
of 
application 
that 
run 
only 
on 
windows 
that 
I 
need).  
Both 
with  
good 
SATA 
hard 
drives 
are 
quite 
responsive.

the

and 
that 
is 
the 
$300 
difference 
in 
the 
Q6600 
and 
the 
Q6700. 
Currently 
I'm 
happy 
with 
my 
E6400 
& 
E6600.
