I would switch to AMD64 if you are comfortable with reinstalling Debian. You will see a performance increase, even on a minimally spec'd system. (I'm not sure its possible to convert a live install from 32-bit to 64-bit). Phoronix did some testing with Ubuntu 32-bit vs 64-bit, and even with a low amount of ram, the performance difference was substantial. This benefit *should* apply to Debian as well. This test was several years ago, as well. http://www.phoronix.com/scan.php?page=article&item=ubuntu_x86_1304&num=4 As for software compatibility, even with AMD64 Debian installed, you can still execute 32-bit code.
