    Right, I have Vista Home Premium installed on my pc. It is 32 bit. I am a little cofused though, so hopefully one of you experts will point me in the right direction. I know I have 32 bit but what are x64 and x86????? I have looked at my computer properties and my system is a 32 bit but what is the actual difference???What do I need to upgrade on my pc to be able to accept/run either x64 or x86???? Is it a big difference anyway????

    X86 is 32 bit
    X64 is 64 bit..

    x86 comes from the Intel part numbering scheme for CPU chips:

    8086
    80186
    80286
    80386 (sometimes called '386)

    Pentium thru Pentium IV

    The "X" represents the general family of xxx86.

    The big difference is the way the OS accesses memory, or indexes it..Whatever..:eek:

    A x86 chip has the capabilities of 32bit and 64bit. I'm running 64bit on a x86 CPU right now!

    One of my mates has borrowed me his Windows Vista ultimate cd rom. It is the x64 or rather 64bit. As I said, Im running Vista Home Premium 32 bit. Should I take a chance and install it???? What are the advantages of Vista Ultimate as opposed to Vista Home Premium???? Thanks Guy's

    If you haven't already, install Everest. Then check with the Everest CPUID under the tools tab. Under instruction set it will tell you if it is 64bit capable.
