    I know that they're supposedly x64, but I read somewhere that, for example, the i5 has "4 x86 cores". What does that mean? would it utilize less of the CPU when running under a x64 OS? Got a bit confused.

    I believe the Core i5 is x64, from what I understand, they are i7's with hyperthreading disabled and lower clock frequencies.

    Correct me if I'm wrong.

    Also, I believe all of the Core series are/will be 64-bit capable.

    All Intel CPUs since the Intel Core 2 Duo are 64-bit. So also the Core i5 and i7. Most computers these days have at least 4 GB of RAM, so 32-bit-only CPUs are useless.

    Thanks for the assurance. Just yesterday installed Win7x64 on my i5. Detects all the frequencies and everything correctly as well as the 4GB.

    A side note: I wasn't even aware that x86 is so much on the brink of disappearing...
