    Hope this is in the right place, hard to know where to put it!

    Basically, I have a windows gaming rig in need of a new gfx card, I want one with mini display so I can use my 27" iMac as an external monitor. Can someone recommend a suitable card for hopefully around $200-$250 that will do the job for me? I have Battlefield 3 in mind for my next purchase so needs to be able to handle that ok.

    Thanks folks.

    Here's an XFX HD 6950 with two MDP ports. One of the first reviews claims excellent performance on the BF3 beta.

    Only AMD offer MDP ports on some cards. So for good performance you'll be wanting a 6950, 6970 or 6990, these will all handle BF3 - just a matter of picking the brand you like (Sapphire etc) with the right ports.

    Couldn't you just get one with a DVI or HDMI output and use a DVI-to-MDP or HDMI-to-MDP cable? We bought an HDMI-to-MDP to hook a Macbook Air up to a Samsung LCD with HDMI and that does the trick... I don't think the fact that you're using an iMac as the monitor would make a difference either.

    You don't need a mini DisplayPort on the graphics card - a regular DisplayPort will work just fine too. My gaming PC has a Radeon HD 6950 that has a regular DisplayPort on it and it powers my iMac's display perfectly well with a DisplayPort -> mini DisplayPort cable I bought locally for like $10.

    As a plus, if you have speakers connected to your iMac, the audio from your PC will actually go through the DisplayPort and be routed by the iMac to its speakers. It's a pretty neat feature! I'm not sure if that'll work with a HDMI -> MDP adapter, and it definitely won't with a DVI -> MDP one.

    In the end i've gone for a gtx560 ti, so all I need to hook up will be a mini displayport to hdmi adapter, hdmi cable obviously, and run in external display mode. Right?
