    64-bit scores for the 27" 2.7GHz i5 where roughly the same for us, in the mid 8000's.

    How do you 'run' OSX in 64bit?

    Glad i'm not the only one who didn't know about this!

    By default it boots into 32bit but if you hold the 6 and 4 keys until the apple logo comes up then it boots into 64 bit mode.

    there is a way to permanantly set it to 64 bit via a terminal command but i don't think I'll risk that yet!

    sorry if i am a bit of a noob here but ...what exactly are the perks of running it in 64 bit? and are there times when doing so benefits the user from a better performance perspective?

    I'm surprised the iMacs don't boot into 64-bit kernel by default. The 2011 MBP do so OTB.

    Benefits of booting into 64 bit is the ability of the kernel to address more than 4GB of RAM and manage system RAM more efficiently.
