Which one of the two models of AMD Athlon 64 3700+ is best?

[Machine_Maker]

AMD has two models of the Athlon 64 3700+ CPUs. This link to the AMD site shows the comparison of the two CPUs( AMD Athlon 64 3700+ comparison ). The difference is the stepping and the voltage. What is stepping and which one of these is the best CPU and why? Thanks in advance.

-------------------------

It might take a lot of searching and reading on the AMD site to get precise answers as to the difference in these two, but in general, a higher stepping number means a later revision to the cpu code. The variable voltage is much tougher to explain. I researched that point a year ago, but I have forgotten the explanation. What I do remember is that it is irrelevant. Bottom line? Go for the higher stepping number, because it is a later revision. I want to point out, however, that whatever was revised in the code may have absolutely no advantage for you compared to the earlier stepping.
