@Javil: 64bit means a maximum address space of 2^64 bytes, which means 16 terabytes. The current 32bit OSes have a maximum address space of 2^32 bytes, which means 4 gigabytes. The maximum address space is usually divided into sections for OS and programs, in the case of Windows there's 2 GB address space per program, and the upper 2 GB is used by the operating system. A 64bit program running on a 64bit operatiing system and 64bit hardware will have an enormous amount of memory available (either physical or virtual). The out-of-memory problems 3D users often run into will be something of the past - for a couple of years, at least.
