The sweet spot for memory size is around 10GB for a hugemem 32-bit kernel. At 
16GB or more, I would definitively go for a 64-bit kernel if possible.

So both machines have 6GB, or 2x3GB?

And if it turns out that there is a God, I don't believe that he is evil.
The worst that can be said is that he's an underachiever.
