Whether installing 64bit OS is better than 32bit in a 64 bit PC?

Question

Hallo friends,
Now a days 64bit PCs are more common. But I think Operating systems and programs have not attained  capacity to fully exploit the power of 64bit machines. (Of course Linux is better than MS counterparts in 64bit zone). If it is sensible to stick with 32bit for better experience in terms of stability and performance? What are the pros and cons of both methods? How we can attain maximum from 64bit PC?   Since every one with a 64bit PC have tried both architectures, feed back opinions and suggestions in the above thread is anticipated from everyone.
Thanks to all

I've made some tests with current Arch i686 and x86_64 on a old AMD Turion 64ML-30
MD5 Bruteforce attack:
i686: 43,5s
x86_64: 31,2s
import md5
import sys
haslo = 'kogut'
hasz_hasla = md5.new(haslo).hexdigest()
def make_word(m, base_string=False):
znaki = 'qwertyuiopasdfghjklzxcvbnm'
for i in znaki:
if base_string:
string = base_string + i
else:
string = i
if md5.new(string).hexdigest() == m:
print 'Podane Haslo to: ' + string
sys.exit()
elif len(string) < 5:
make_word(m=m, base_string=string)
make_word(hasz_hasla)
Untar Gentoo stage3 to /dev/null:
i686: 48,3s
x86_64: 42,3s
Make a thumb out of 3,1MB jpeg file with convert:
i686: 1,62s
x86_64: 1,28s
Make avi from Big Buck Bunny with ffmpeg:
(ffmpeg -i big_buck_bunny_480p_stereo.ogg a.avi) making mpeg didn't work on i686 - segmentation fault
i686: 276s
x86_64: 295s
Make mpeg from Big Buck Bunny with mencoder:
(mencoder big_buck_bunny_480p_stereo.ogg -oac lavc -ovc lavc -o a.mpeg)
i686: 263s
x86_64: 251s
