Yea that pretty much shows the intelligence level of this forum. People rant off stuff that they heard somewhere else and have no idea what they're talking about.
Theres a lot of software inplications of 64-bit, mostly for business use. Basically, a 64-bit operating system can be thought of as a "stronger" operating system. Take Vista for example. In Vista you will have about 10 times as many features, just because you can. It also brings about other possible advances, such as the confirmed DX10 (though its not called that).
