Program Files x86 vs. 64

I just installed Windows 7 Ultimate 64 bit version and am confused about the x86 and 64 bit program files folders that I have.

So far all the programs I have installed have selected the x86 folder by default. Will only the programs that aren't compatible with 64 bit default to this folder? Will I get any of the benefits of a 64 bit OS with programs installed into the x86 folder?

Furthermore, which should BF2 be installed to?

x86 folder is for 32bit software and x64 for 64bit software.

If the software is 32bit, then no.

I'd recommend installing all your software and games on a separate partition, not on the OS one. But the answer you are looking for here is x86.
