There's all sorts of interesting stuff in 64 bit windows :)  The user 
mode thread scheduler is pretty cool.

On the flip side: 32 bit is in its twilight days, and I am reasonably 
confident the next game I work on will be the last one that even 
supports 32 bits.  Then I can finally use all the new 64 bit goodies :) 
   32 bits will be reserved for phones and tablets (and even then 
tablets will probably be making the switch pretty soon-ish)
