Are you talking about upgrading? To be honest I say no because of critical driver incompatabilities. So fresh install is better.
As for your pc? Yes you could run a 64 bit OS but it would only function in 32 bit because of hardware capabilities, run Vista? No, you cannot run 32
bit Vista in wth that hardware with adequete functionality.
So what is 32 bit and 64 bit architecture?
Well, like every thinking computer part it reads information in 0's and 1's. And these come in the form of 'electricity on' or 'electricity off'
a bit like morse code. Any single signal on or off is called a bit.
So when we say my processor has a 32 bit address block it can read a 32 bits of address information in any given clock cycle, for example 800Mhz (800
milllion cycles per second fast!)
A 32 bit address:
So you see a 64 bit address is twice as wide and we measure width in bandwidth, so it has double the bandwidth.
Do I need 64 bit? Answer is not likely although it depends on what you do. For me I have 64 bit but I don't see amazing differences yet due to the
fact that software is only just moving towards 64 bit functionality. And I assume your not using programs that require over 4 gig's of memory, if
this is the case then you don't need it yet.

hope this helps.
