With all the hype going around about 64bit operating systems, one wonders whether a change from the standard 32bit system is a good idea. If u a hectic gamer then 64bit is for u. For ordinary office and home applications 64bit has no real effect. My advice for now...stick to 32bit and don't spend a fortune upgrading ur pc to 64bit. Its just not worth it, besides current applications are not demanding anyway.
