My new laptop has an Intel Duo T8400 processor. Should I install the 32
or 64 bit distro ? I run a lot of esoteric open source apps. Can I
run a 32 bit application if I install the 64 bit distro ?
Thanks

I'm running F9.x86_64 on my Intel Core2 T7200. I have a small number of
32 apps installed for those edge cases where the parts either don't
work, or aren't available in 64 bit. nspluginwrapper takes care of most
of those for me (OK, I have to run adeona in 32 bit as well, grumble,
grumble). But, for the most part, 64 bit works for me. YMMV
Thanks

I'm running 64 bit Fedora 9 on AMD Athlon 64 X2, and it works pretty well.
You'll have to use nspluginwrapper for Flash with the 64 bit Firefox, and I've
found this to be a bit buggy. Especially jumping around the NFL website with
game tracking. Sometimes it won't load and you'll get grey boxes where Flash
content should be (reload or page back and click again works to fix). And I
have to grab the 64 bit Enigmail from Remi as it's not in the Fedora repos. I
haven't had a issue running 32 bit apps.
Basically, unless you're doing something where you'll really benefit from the
speed increase of 64 bit, video transcoding for example, you'll save yourself
some headaches going 32 bit. But if you just want to play with 64 bit it's ready.

Other have answered about Firefox. I'm running 64-bit Fedora 9 with a
quad-core AMD Opteron with no problems. 32-bit apps work well,
especially on Fedora where you have the 32-bit libraries installed in
addition to the 64-bit libraries. I also have a 64-bit laptop that has
been running a 64-bit Linux OS for about 5 years with no problems.
Memory management under 64-bits is better than it is in a 32-bit OS.
A few years ago, I did perform some benchmarks and found that 32-bit
apps generally are faster with a 64-bit OS.

I always heard that if you have less than 4Megs Ram, then running 64bit
doesn't take advantage or won't see the Ram anyway, or something to that
affect? I have dual core athlon with 64bit but only 2megs ram, which
under either/or, they only see 1.8 or 1.9Megs anyway. So I just stayed
with the 32bit.

I /really/ hope you mean 4GB of RAM and not 4MB. With 32-bit and 4GB
RAM you generally won't see all 4B (usually 3.5 to 3.75) with the PAE
enabled kernel.
I am personally fond of going 64-bit whether I have 4GB RAM or not, just
to keep packages consistent. I can always upgrade my RAM, it's a pain
going from 32-bit to 64-bit on the OS side.
My $0.02.

Heh, DOH!! I did mean Gigs, not Megs.

We'll see on that, as I first tried out 64bit but didn't really notice a
huge difference compared to running 32bit, least on my system. And
since I use flash and couple others (I think), I have to mix and match
some i386 packages as well.
Who knows, maybe I'll try 64 again with F10 and see what happens.

Why not both at the same time, NOT dual boot?
My laptop features a similar CPU.
When I am testing a 32bit OS, I simply run it in a VM using qemu-kvm.
Right this minute I need to test a vendor recommended upgrade to one of
our production servers, which is a 32 bit machine. So I fired up a VM,
and am currently restoring last night's backup of the production system
(RHE4) to the VM on my laptop.
When that finishes, I will run the vendor supplied upgrade procedure on
that VM and discover any problems.
All that, and more, while typing this.
Good Luck!

The x86_64 family of chips is not just 64-bit. It also has more
registers. Address space is linear rather than segmented. Most desktop
users will not notice the difference between 32-bits and 64-bits
especially if we have under 4GB of RAM. The bottom line is that a 64-bit
Linux OS is generally more efficient than a 32-bit Linux. Linux has been
a 64-bit OS for about 14 years, and there are very few reasons to run a
32-bit Linux on a 64-bit chip. Nearly all PC hardware sold today is
64-bit hardware.
The problem we have is twofold. Some developers just don't want to
maintain 64-bit and 32-bit versions of their code. I think this will
change in the near future now that 64-bit Windows is available for the
consumer market.
