Really!? I have an amd athlon64 running at 1.8 Ghz with 512M ram and I find
gnome and kde run well. I also have a full gnome/kde install and I run them
to their fullest with no problem.
Have no fear, with that box you have there you can load up about anything you
like I'm sure.

Yes, as long as it is a 64bit cpu. What does 'cat /proc/cpuinfo' say? The
64bit system runs just like the 32bit one does, it is the way of the future
(until the 128bit system that is!). You can use (a lot) more than 4G ram with
a 64bit system.

As Michael said the device names change from a 2.4 -> 2.6 kernel, a long with
a few other things like that. I would follow what he said and change your
fstab accordingly and see how it goes. My system runs sarge amd64 nicely but
some folks have problems with hardware (sata), you may need to upgrade to
etch to get hardware support if sarge won't go.
