As for 64-Bit applications, I am still not sold on the fact that a patch will convert it to operate to the full potential, compared to being written from the ground up. In the article, I've used Far Cry 64-Bit and Sandra 64-Bit, both of which didn't show any performance increase over their 32-Bit counterparts. Simply put, there is no reason to want to get the 64-Bit version of the OS, especially since it still has compatability issues, and decreases performance in some tests. Aquamark3, for example, does not work in x64. That's just not worth the ~$170US price tag.
