Siding with most of the group (go amd64), I'll add my own comment: Using PAE to access 4G of RAM (because 4G shows up as 2.5 to 3.5 gig, depending on the motherboard) under i386 is a reasonable solution, IMHO. Maybe even 6 gig or 8 gig... if you're trying to extend the life of an ia32 server. But with amd64 supporting ia32 binaries well, it seems the only reason left might be drivers --- except ... are there _any_ drivers that support PAE and _not_ amd64? I'm using amd64 on my laptop (which has 4gig) because the only driver I care about (the nvidia binary driver) doesn't work under either PAE or amd64 (and ... it also doesn't support 8xxx series mobile chipsets ... so I'm screwed anyways) . I'd be curious to know if anyone's still hedging their bets by making their machine dual-boot i386/amd64 --- and how they configure it. Have you thought about sharing /usr or parts of it? Installed ports can seemingly mess things up.
