What is the recommended architecture to use for Intel's Core2
(Dual/Quad) processors?
I have two computers I'm considering going amd64 on:
...
I've found the following (likely incomplete) list of things that may
affect the choice, or might be affected by it, are:
- Memory (4GB limit)
- W^X
W^X is available on most OpenBSD platforms, including i386 and amd64.
- 64-bit instructions
as a user, you don't execute instructions directly, so this is mostly
just "bigger is better" hype, the same reason people get excited about
seeing all their cores in their dmesg on an app that a 100MHz Pentium
could do just fine on. Most of the same apps work on i386 as on amd64,
you really don't care what instructions are being executed (or how
many bits are in 'em) to make them run.

To be honest, most users probably won't see a difference. Me? I'd
probably go with amd64, as practically speaking, i386 is slowly
moving into the "legacy" category. I say "probably", because I would
very possibly forget and accidentally install i386 on it. :)
Ok, based on the fact that I did that today already, let's say I'd
SUGGEST going with amd64, even though I'd probably forget and go with
i386 myself. :)
