Ok so I needed a new computer and so I decided to build it myself so I bult a 6000+ amd 64 dual core with 2gb RAM, and ext... and when I was at the store buying the parts the guy asked me if I wanted the 64 bit version of Vista, which was the same price so why not get it, but now that I have the computer up and running I haven't noticed any difference between 32 bit and 64 bit, so what is the difference?

I run the 64-bit version of Vista and I enjoy it. Given the low amount of RAM you may not get the full benefit of using a 64-bit edition. This is due to the fact that the 32-bit allows for approx. 3 GB of memory whereas the 64-bit variety allows for far more RAM, about 16 exabytes. If you have a motherboard which supports 4 or more gigabytes of RAM and a 64-bit processor, 64-bit Windows is a good choice. The 64-bit edition of Vista also includes some security features the 32-bit does not. Including: Address Space Layout Randmonizer (ASLR) that helps eliminate remote system attacks for the first time on the Windows platform, NX bit implemented at the hardware level, which helps to prevent the buffer overflows that are commonly used in electronic attacks, and kernel patch protection (PatchGuard) which blocks software from changing the kernel. But, there's a catch. All drivers for the 64-bit edition MUST be digitally signed in order to be used. This is not a huge issue if you have newer hardware. Hardware manufacturers, if they want to be part of the Windows Vista Logo Program, must produce both 32 and 64-bit versions of drivers. Also, 32-bit applications run in WOW64 mode (32-bit emulation) and compatibility is not guaranteed. I've been using 64-bit Ultimate since February and I haven't had any compatibility problems with my games and programs.

If I had reliable drivers for my system, I'd be using 64 bit right now. But the driver development for 64 bit hasn't matured quite yet. Lot's of folks can use it without issues, but those driver issues that do crop up are killer. If it's working fine, then don't mess with it - but make sure that any new hardware that you purchase has 64 bit drivers.

If you do decide to go to 4GB or more of RAM, you may need to adjust a setting in your motherboard's BIOS to allow it to see all the memory. On my board, it's called memory hole remapping, your motherboard may call it something different.
