The main difference would be related to memory accessibility. 32bit systems can only address 4GB of memory. Where 64bit systems can address much more than that.

With 32bit everything is reffered to using 32bits, with 64bit the computer uses 64bits instead. 64bit programs run faster on a 64bit OS than a 32bit program as you are handling more data at a time, though there isn't a huge amount of 64bit programs. You also get access to more volitile memory (including RAM, VRAM, cache ect) (2^64 (17,592,186,044,416gb) instead of 2^32 (4gb).

oh yeah, that should be mb, either way no motherboard supports that much, you won't even find server or super computer with that much RAM
