AMD Athlon64 X2 3800+
 

A few months back we took a look at a couple of AMD's X2 CPU's in the form
of the 4800+ and the 4400+. Both provided excellent
performance in all tasks however they did come at quite a hefty price.
Since publishing those articles AMD released the 3800+ which
provides AMD users with all of the benefits of Dual Core computing -
however at a much lower cost. Aimed to compete directly with the
Pentium D 820 in terms of price and performance we were very interested to
see just how well the new chip would compete with our previous
Gold Award winner.
