Basically i am just doing mainboard and CPU Upgrade but a hefty one i think now

here is the question and thank you in advance for any help i get

If i choose a 64 Bit over the 32 Bit what are the advantages/disadvantages?
If i do the 32 bit over the 64 bit there is a CMD line that will show i know up to atleast 6GB in a 32 bit Vista but can windows or programs use it with that line inserted?
(BCDEdit /set PAE forceenable)
Will i see more or less than 10% boost in performance? either way

The other upgrade i might do in the soon feature is the video card upgrading to a XFX 275GTX
I will keep the 8800GT in the computer as a dedicated Physics GPU

A 64 bit OS can essentially use (actually put to work) more than 3 GB of RAM. A 32 bit OS can only recognize around 3 gigs (I think it's closer to 3.2), and therefore runs as if it only has 3 GB of RAM, even if you have 20 gigs. At this point in time I agree with baddad, there is no reason to not get a 64 bit OS.

I went to an event for the intel retail edge and i Won the motherboard and CPU combo it's at this moment sitting on my couch in the living room and all i really need to buy is the Ram

The Corsair Dominator line with memory module cooler
are great, and the fan is extra insurance of reliability
and stability, especially if you decide to overclock:

p.s. With Windows XP/Pro 32-bit, you can utilize unmanaged Windows memory
with RamDisk Plus from www.superspeed.com :

Such a ramdisk is a good place to host your browser cache(s),
and possibly also the Windows swap file "pagefile.sys".
