You are essentially saying that "a 64-bit OS runs faster than a 32-bit
OS". I've _never_ seen this to be the case and that factor is thus
never a consideration when deciding between 32-bit and 64-bit for me;
the only considerations are, generally, (i) support of proprietary
software/plugins - if important, this favours 32-bit on the whole, and
(ii) support for Lots Of RAM - if important, this favours 64-bit.
I don't believe what you say is generally true. Can you provide any
references to back up what you say?
