So I think its too early to install Win64 since there is very few Windows software that is developed on it. But if you really awnt 64 bit Windows, try to check if all driver (and programs) you use is supported.
64 bit windows is programmed to let 32bit programs access way more pagefile space than ordinary windows 32bit.
The only problems you will find is that still some new games use 32bit installers and may have a 16bit cd checker utility like Area 51 does or it can have a 16bit installer and still be a 32bit game like the old star trek voyager elite force. If either of these cases are true, you will not be able to use that software. Oh that means games like the original Deus Ex and Ghost Recons and Star Trek Klingon Academy will work though because the system manages to make the 16bit installer if it has that into a 32bit installer and 32bit program.
I perfer x64 Windows XP over FC3, FC4, FC5 because of it being easier to use and it works great with my hardware set up. You didn't say what manufacture of your laptop you use. But my desktop is a Gateway Desktop and it has lots of propreitary stuff on it and it runs better in x64 than any Linux distro.
That just my observations...
