Both 5.3 and 5.4-STABLE have been running fine on my Athlon64
Athlon64 3400+ (2.4 GHz, 400 MHz FSB)
MSI Neo FSR (MSI-6702) [VIA chipset]
2x512 MB PC3200U-2533 RAM
Nforce3 and 4 chipsets seem to have some problems, see the mailing list
archives. Same goes for the ehci driver.

Run apps that are multi-process or multi-threaded. :-)

Some mobos had problems with ACPI on 5.3. For those mobos it has to be
disabled. This might be solved with 5.4.
If you're transplanting a make.conf from a machine with another
architecture, remove any --march options from CFLAGS and COPTFLAGS.
Same goes for the 'machine' and 'cpu' lines in your kernel
configuration if you copy that from a machine with another architecture.
FAST_IPSEC is seems to be b0rken on amd64.
Look at the open problem reports for amd64.

All apps that I use for common desktop use are fine. Emacs, Firefox,
To find a list of all the ports that are b0rken on amd64 try the following:
find . -name Makefile | xargs grep -H "BROKEN.*amd64"|sed 's|/Makefile.*||'
If a port is marked BROKEN on amd64, it could just be that it wasn't
tested on it, or a previous version was broken. Try removing the "BROKEN" line
and see where the build fails. Sometimes the fix is trivial.
