64bit vs 32bit

[Lan4ear]

From programs perspective, does it worth installing 64bit?

What programs wont work for me? Does most programs got 64bit compatible versions?

[not important]

For me, no. I hear stories of faster speeds and more security but that's just what I hear. As for softwares, I would suggest checking the software websites for 64-Bit compatibility.

The software must be 64 bit compatible, but everyday there is more and more 64 bit capable software available. I'm happy with Vista 64 and have been using it more than Vista 32 or XP32 (mine is a triple boot).

So far it has been relatively stable and fast. Its nice knowing your CPU is being used as a 64 bit processor and all of your RAM is being recognized. As far as games go, Crysis works faster on Vista 64 than XP 32.

You can get an OEM version of Vista 64 for under $100 bucks, so what have you got to lose for trying it?

The software does NOT have to be 64-bit compatible. The 64-bit MS OSs have a 32bit emulator called WOW64, and you should be able to run most if not all of your current software. I have only installed probably 7 64-bit native programs, and the other 30 programs I have are all written in 32-bit (or x86 for fanatics). I've had XP Pro x64 for a while and have had no issues, except for installing old games (before 2005). Some have driver issues with printers and scanners and such, but sites like http://www.planetamd64.com/ have drivers for all types of hardware. You should be fine and quite and enjoy the upgrade.

Perks I enjoy: less viruses as pretty much all viruses are written in 32-bit format; more ram, you can use up to 128 GB of ram (check your motherboards limit though); ect.

ps. To touch what David said, some programs come with both 32 and 64-bit versions in the installation, like Crysis.

One of the biggest perks is more RAM: if you have 4 GB of RAM or more, 64-bit is the only way to go. I've been using Windows XP Pro 64-bit for more than two years, haven't had any real problems with it. Sure, a couple old programs wouldn't work, but nothing important. There are 64-bit drivers for just about all modern hardware out there.
