    Hello all! So I have late 2009 27' imac, running ati 4850 vga. lately vga started to throw out artifacts after sometime of playing or doing video editing, so I think my vga is dying... Tried to reset PRAM, didn't help, worked fine for a half an hour, but after playing diablo 3 for a few mins artifacts appeared again, same in bootcamp.
    So I thinking of upgrading my vga to ati 6970m, but for an apple branded card price is insane. I was thinking, maybe its possible to reflash vga cards BIOS to apple bios? Because you can get a 6970m from dells alienware for a half price of apple. Maybe somebody tried it? thank!

    Unfortunately, I've yet to come across information for flashing MXM cards to Apple firmware... despite a lot of searching. :eek:

    I think its not that popular, like lets say flashing vga cards for hackintosh, but any way, its possible to flash mxm cards for laptops. Also you can download apple bios files from techpowerup dot com for 6970m, just interesting is it possible and how to flash them.

    So as far as I know, if the card not from apple you cant see a boot screen, its not a problem for me at least, but how to select windows(bootcamp) to boot? Also I have found really nice deals for non-apple branded 5870m cards, but they have never been available for imac from apple, interesting would it work?

    Also wrote an email to local apple dealer, just curious how much did he charge for replacing card...

    Imac VGA repair

    Maybe you can consider repairing it. There should be a number of service shops near you which can do the job and there is also a repair offer for such boards on ebay for less than 50Euro http://www.ebay.com/itm/261363797170
