    Hey guys, hoping you can help.

    Right basically i have been looking at getting a GFX card with the mini-display port on so i can hook this straight up to my iMac.

    I just need some clarification on if this will defiantly work with money being tight and i don't want to waste my money.

    btw does anyone do this?

    The parts I'm ordering will be:

    The belkin Mini-display port to Display port cable

    Also whoever has done this, is it worth having it on the iMac 27inch for gaming? thanks in advance.

    GFX Card to go in the PC with display port

    What iMac? The current 27" only accept video input from Thunderbolt.
    Last gen 27" accepted non-Thunderbolt.

    I saw on Amazon that someone used a version successfully with my iMac model, which is late 2009 27". It was an XFX Radeon 6870. But you better check with the manufacturer.

    I'm running crossfired 6850's into a 2009 iMac 27" mini display port, works perfectly. Avoid 5xxx series Radeons, they had an issue with a MDP bug and generally don't work but 6xxx onwards should work fine. Nvidia cards with MDP should work too (although they are rare).
    It's well worth doing, the 27" iMac is one of the best displays around.
    Long discussion thread on HardOCP about this.

    I have a 2011 iMac with a 6970 Radeon, and I was wondering if it is possible to add a second external radeon 6970 via a thunderbolt or video port.

    Do you mean a second iMac as an external display?

    No, I was wanting to have two cards running together. One internal and one external. Using the one 27" monitor. This is to run high intensity simulation software. I couldn't work out if that's what post #4 meant.

    Can iMac run GPU's externally? I've never heard of that. :confused:

    I don't understand. How would you get an external GPU to work? You can't drive one monitor with two GPUs.

    The external cards are meant to work in a PC, not a mac.
