It would be helpful to know of any other gains. 32bit systems are limited to 4GB of main memory, but many motherboards limit that further to only 2-3GB . This is wrong. 32bits systems can use up to 64GB of RAM, with 2.6 Linux kernels... It's just a matter of compiling the kernel with the right option: Processor type and feature --> High memory support --> 64GB (HIGHMEM64G) Henri. When someone buys a Compaq Presario Home PC, you can expect the common person who buys such a pre-built system won't be  one to uninstall Windows and install a custom Linux Kernel. Such 32-bit pre-built systems were being sold even after 64bit systems arrived, and the 32-bit system were limited to only 2GB! What I said is not wrong, especially if you consider what is supported in common systems that people buy. A bit of common sense, please, and you'll see when I said limited that I meant by practical limitations and not what you thought as technically possible.
