For machines with less than 4GB of RAM, running 32-bit version is probably
wise; 32-bit processes use memory more efficiently compared with 64-bit mode.

For some math-intensive workloads like SSL/crypto, audio/video transcoding,
and such, there is likely to be significant improvement in 64-bit mode
compared with running in 32-bit mode.  For most other workloads, you're
not likely to notice a difference.

Nope, or at least not in general; AMD64 is very stable nowadays.
