Stan:

BiaB 2010.5 (but not earlier versions) works with Win 7 64-bit; but I've run BiaB on both the 32bit and 64bit Win 7 (on the above AMD/ASUS computer) and I can't see any performance difference. I think the chipset is much more important -- as I said, the 4 cores give you about 3 times the processing of a single core with BiaB, and because Win 7 is assigning tasks to chips, the load balancing is very good across cores on the 4-core chip.

Another thought .... Win 7 32 will support almost all applications (down to Win 95 compatibility) whereas the 64 bit supports a much smaller set of apps (importantly, a lot of the free utility apps for sound, video, compression, etc. only run on 32 bit Win). This mainly (to me) means that Win 7 64-bit is a PITA; So I've settled on Win 7 32bit as my standard (and I do think Win 7 is much better than Vista)
