However, its rarely more than a few percent. Hardly noticeable, really. On the other hand, many compute intensive applications that can make good use of the improvements in the 64 bit instruction set really fly in a 64 bit build, compared to a 32 bit build. The memory footprint of 64 bit builds can be larger, but its not usually by much. Overall, if your pentium/athlon machine can run a 64 bit system its hard to imagine a sane reason for not doing so. The few things you must still run 32 bit, like firefox + flash, run just as well on a 64 bit system as on a 32 bit one.
