    Hi guys,

    I'm thinking in borrowing a GTX680 (PC) from a friend to test on my cMP (MP4,1) with El Capitan.
    However, I only have a single 6-pin cable.
    Is it safe to test?
    What should I expect?

    My understanding is that:
    - the card does not requires drivers in recent versions of OSX since the iMac13,2 has a GTX680MX (which I suppose is very similar)

    Do I need to install the drivers anyway?

    I just won't work without both cables plugged in. Black screen.

    Thanks Fl0r!an !

    Does anybody knows where can I get those cables in the EU? (outside eBay, I don't want to wait too long)

    I walked into a tiny, random computer repair store on the street and asked if they had any. Feels like a lot of those places have old Mac Pros sitting around unused in the back to be cannibalized for parts – they were happy to pull one and sell it to me.

    $8 and they ship worldwide. It's from the USA though.
