x86_64 is the common set of configurations and libraries for 64-bit
computers. You should be able to look up the model number of your
computer, or the motherboard and BIOS at boot time. Or you can grab a
live CD, such as the CentOS 5.4 or Ubuntu live CD, and boot with the
64-bit live CD to determine if it's compatible with your system.
If you can, use 64-bit operating systems. There are some lingering
compatibility issues, but you can make much more full use of your
hardware with a 64-bit operating system, and virtualize a 32-bit
operating sytem if you need it. You cannot do the reverse.
There are other architectures, which a home PC is unlikely to have.
These include ARM (common in some fascinating netbooks and
smartphones) and sparc (no longer in production, Sun computers got
bought).
