Personally, I'm not a DD (debian developer). This is the amd64-specific
user forum. You're a (prospective) user, so its foru. :-) Subscribe to
the list and listen in. You'll get the flavour.
Ram limits are main-board specific. I recently bought an ASUS M2N-SLI
Deluxe amd64/AM2 which can take 8GB max. I too wanted to make a box
that would last a long time (I write this email on my 486) and lack of
memory upgradability is what for me makes a box less and less usefull
over time. Actually, my 486 does everything it ever did but when it was
invented, video editing and DVDs hadn't been invented. Neither had the
how cheap will a new amd-128 (256?) with 100 G ram and 10 T drives be?
Maybe someone will compile gnome for MPI and you can have a 5 box
cluster to keep the mouse and eye-candy moving.
There comes a point where the memory limit is one of bandwidth not
physical size. At that point it makes more sense to have two smaller
CPU/memory boards/boxs than one huge. Hopefully it will be a long time
before gnome gets bloated enough to need this.
The other half of longevity is physical longevity. Get a big enough box
to take adequate cooling (more, bigger fans can run slower and quieter
than a couple of tiny ones to move the same amount of air). I went with
the Cooler Master Stacker and CM iGreen 600 W PSU.
Actual debian installation is the same as i386 (actually, this is as I
understand, since I didn't try i386). You check the debian web site to
see if a package you're interested in is available for amd64. As I
understand it there are a few things that aren't (yet?). I think that
flashplayer is one. Some 32-bit apps can be run from within the amd64
through the use of 32-bit libs (there's a package for this). Others
have to be instaled in a i386 installation within a chroot. I haven't
done this but I understand its simpler than it sounds.
