3stripe, the Intel Core Duo is a 32bit chip. Bootcamp doesn't emulate anything, it just installs a boot manager, much like the way you would dual-boot Windows with Linux. So the answer is definitely not, I'm 100% sure.
You probably wouldn't want to run 64bit Windows anyways, I've heard it's buggy (*cough*). Stick with OSX
I bought a Core Duo lappy, 1.66 GHz and it is awesome. Not a mac, but a Vaio, but much faster than my 1.8Ghz Centrino.
I reckon the extra 'sparkly 3D' features of Vista will make any hardware performance increases redundant lol.

If you want 64bit then wait for Vista. Then again, the Beta version of that have been buggier than the 32.....
Shit.
I'm gonna pop in the 64bit edition of the Ubuntu live-cd and see if that's true. If it is, I'll be pretty happy
