Hello together! I'm using an iMac7,1 24" from Mid2007 with an Intel C2D Extreme and HD 2600 Pro Graphics Card. It is upgraded with SSD and RAM to its Max, but now the graphics card is failing, producing fractals (always visible in the upper part of the screen), and sometimes stripes with other graphic errors. I've already read about upgrading the graphics card on an iMac 2011: https://forums.macrumors.com/threads/2011-imac-graphics-card-upgrade.1596614/page-30 Is this similar to my iMac7,1 according adaptation of possible EFI problems / flashing? I'm thinking about replacing the graphics card with an higher model, but I'm not sure which MXM Slot is used in my model. MXM III? Does an MXM GTX770 fit, both the slot and the height? Or any similar, newer graphics card? An adaptation of cooler / fan should not be that problem. Kind regards, Daniel.
