    I'm getting Win 7 and I do alot of CAD, 3D rendering, Photoshop, Lightroom, and heavy computer programming (Visual Basic, Ruby on Rails, Matlab, etc.). Which would better suit me? I love to leave the lappy on and keep many things open at once. I thnk I'll strip Win 7 down to XP mode..

    If the software is not based on 64 bit, it is no use that you have a 64 bit OS. That is the rule.

    If your processor is on 32 bits - Install Win 7 x86 ( 32 bits )
    If your processor is on 64 bits - Install Win 7 x86 ( 32 bits )
    If you have more than 3 GB ram and 64 bits - x64

    64 bit is overrated speed-wise, to make it work you'll need:

    1. 64-bit cpu.

    2. 64-bit os.

    3. 64-bit program.

    If you don't have all of those then everything will actually run slower than 32-bit due to
    too many empty bytes that must be processed.

    "64-bits" really refers to the bus that connects the CPU to memory where the program instructions and data are stored. In theory, the 64-bit wide bus allows you to fetch larger chunks of data for operating on, or to fetch and execute two or more instructions at a time, thus running a program faster.

    The downside is that "empty bytes" may still have to be processed: unless the micro-code (ie, the CPU's internal OS) is structured to indicate how much of a 64-bit chunk is to be processed, "empty bytes" will still have to processed, which wastes CPU cycles.

    Then there's the assumptions about bus width built into the programming language's compiler or executor. These are OS and BIOS concerns.

    Also some companies don't provide 64 bit drivers for components.

    If you have a newer machine with 3 or more gigabytes of RAM then go 64-bit.

    64bits is more comfortable than 32 bits so you should buy 64 bits windows

    32bit apps can run on 64bit os.
    If you need more ram (running apps like AMR, XR,... or VMware), go for the 64bit as you will need a lot of RAM.
