    Is Core 2 Duo 'real' 64bit based?

    No PC CPU is "real" 64-bit. The 64-bit support is in the form of extensions glued on top of 32bit extensions glued on top of a 16-bit CPU that is made to be compatible with an 8-bit CPU.

    So it's a far cry from "proper" 64-bit CPU's, which aren't used in PC's.

    But yes, the Core 2 is as "real" 64-bit as an Athlon 64 or any other PC CPU. :)

    so i have an CoreDuo T2050, it`s only 32bit, will it not work with an 64bit operating system at all?

    regards.

    No, it wont. If you want to use a 64 bit OS then you will need either the Core 2 Duo or any AMD(Athlon/Turion/current Sempron) series processor.

    Can you install 32bit apps in a 64bit OS?

    Yes, at least if you are talking about XP X64 or Vista 64bit.

    You can try Itanium processors. They are almost pure 64bit because the 32bit runs very slowly.

    What do you mean? (Or who were you replying to?)

    Anyway, yes, a 64-bit CPU can run 32 or 64 bit OS'es, and a 64 bit OS can run 32 or 64 bit applications.

    (And by 64-bit CPU I mean Core 2 or Athlon/Turion, and not any "pure" 64 bit CPU's)

    Most of the time yes. However, it doesn't work the other way around; 64-bit apps cannot be installed on a 32-bit OS.
