I'm looking for a laptop - and have a question regarding the processor id/number.

I know how it goes in a desktop - example: a 530 process is the old 32bit, 3.0ghz while a 630 is the 64bit proc, 3.0 ghz.

But on a particular intel laptop, I read that it has a 730. Well...is that a 32bit or 64bit? I want it to 'live' a while - and want the 64bit proc so that it may one day run Win64.

Or - should I give up and simply get one with a Athon 64?
