At work, we run Windows 7 Professional 32-bit because although our computers can technically run 64-bit, there are no audio drivers for the 64-bit version and there is some software we support that does not support 64-bit at the moment. Additionally, these PCs only have 1 GB of RAM so we would see no benefit.
At home, I run Windows 7 Ultimate 64-bit because I have 4 GB of RAM and to fully take advantage of it, I need to run a 64-bit OS. I don't really a huge performance increment going from 32-bit to 64-bit as I don't really run data intensive applications that require a lot of RAM.
