you can find on ebay dell hd6970 2gb version or iMac video card amd radeon hd6970 2gb which is already flashed, it's very complecated to flash a video card on imac, you need to install first a windows with old card, then set start up windows by default, then change to the new card and start up windows, do the flash thing, restart to mac menu voir si ca marche
