The first question is the amount of RAM you have, if it's around 3GB, you will surely want to go with i386, if it's above, you will need to consider the following.

Virtually all ports work on i386, but some don't on amd64 (yet), for example wine (emulation), nvidia-driver (in case you want to play 3D games and have an nVidia card), but some others like valgrind or xnview. Depends on your needs (and hardware).

Also, other point for choosing distributive - ports with re-mark "broken" more on amd64. So, i386 have almost anything software (for desktop).

I use amd64 on my notebook. Mainly desktop use. The only thing I miss is suspend/resume.

Really? Is the no way to use more than 3gb in FreeBSD 32? I read about PAE, but its not enabled by default and doesn't seem to be stable....

This is a problem with all 32 bit OS's. Not only FreeBSD.

It's stable but to make full use of it applications (and drivers) need to be able to handle PAE.

It's very interesting topic. I tried amd64 on 7.1 and I only got problems with some applications. In general x64 is still experimental and gives no any advantage (unless you have really large ram, like 32GB or so). Despite x64 do recognize memore above 4GB but it also uses double for its adressing.
I even read an opinion that x64 is only to rise their sales at the moment :)

Yup, and quite a few drivers aren't PAE compatible or are untested. More details in src/sys/i386/conf/PAE.

linux-f10-flashplugin10 - works on amd64, some movies causes SEGV on seek, others not.... looks like flash-related bug non amd64 related

Ah, does it? When I tried 'make install clean', it died with a message saying it required i386. Maybe I did something wrong -- my bad.

Since nVidia added support for AMD64 recently and I figured out how to set up wine, I've seen no particular reason to go back to the 32bit version. I'd personally rather run code that makes the most of my processor where possible.

But it really depends on how badly you need those 32bit ports and how much you dislike compiling them in 32bit mode.

Just wanted to add my $0.02 about i386/amd64 ...

I recently upgraded my box to 3 x 1TB drives and wanted to use ZFS on them, but ZFS does not like i386, well maybe in triangle with kernel panic ...

I was 'scared' about flash and wine on amd64, but after installing amd64 I am very positively surprised.

Flash works without any problem in amd64, even the installation methond is the same (all ports/packages with f10), VirtualBox works as usual, even wine installation is posible without much trouble.

Workspaces switching on my window manager seems little more snappy (dunno why ...), ZFS works as desired, does not panics at unixbench benchmark (I only limited ARC to 128M).

I need to try amd64 on my laptop, suspend to ram should be working on amd64 with SMP ...
