32bit vs. 64bit

[pjmoses]

I am curious as to the difference between 64bit and 32bit Windows 7. I am installing a new Vertex 3 SSD and know the 32bit is a smaller file. Does it run as fast as the 64bit? And does it have the same features? I am trying to save some space and it seems like the 64bit takes longer to load. What difference would it make if I installed the 32bit instead of 64 on my new drive? Would programs not be more compatable also? I just do not get the reasoning behind 64bit when it comes to speed.

The instruction set is the main difference, along with x64 taking a little more space for install and a very very small performance hit when x64 running x86 code.

I think most people would agree that x64 is the way to go, except when you have 2GB of ram or less, netbook or low power laptop.

I was just trying to get all out of a new Vertex 3 SSD is why I am asking. And space is at a premium with those @ almost $3 a gig.

Functionally, Win7 is the same other than x64 requires 64 bit drivers. If you never plan on installing more than 4 gig of ram (~3.5G usable) then go with 32 bit, otherwise go 64 bit.

I have 8 gigs installed with another 8 to use for Ramdisk.
