Jeff, That's true in many cases but not because there no gains in performance. There ARE very significant performance gains for processor intensive applications. Many applications simply run into other bottlenecks (I/O, bandwidth, DB etc) before they start really pegging even the 32 bit processor. We had a site running 32 bit procs (dualproc/dualcore) that was running at 70% and servicing a few hundred thousand visitors a day. On CF 64 the procs look pretty much idle most of the time with the same amount of traffic (upgrading to MSSQL05x64 helped too :). Another example - If you are doing abstract financial calculations you can get exponential gains by moving to 64 bit - with or without CF. Moreover, I suspect that we are close to a tipping point on 32/64. I'm certainly seeing a lot more new 64bit hardware than 32 bit at the moment. So I would suggest moving in that direction to keep from falling behind if for no other reason. In my mind it makes little sense to purchase 64 bit hardware only to run 32 bit software and OS on it.
