I’ve had the same issue with my 4 core as others are reporting. It worked perfectly for 9 months initially before getter by the freezes and the gpu restart and window server errors in the log


When I initially took it back they ordered the 2 graphics cards, interconnect board and ribbon cables. Someone in Apple support blocked the ordering of these parts and only the cables were replaced. This fixed it for a few months.

I’ve since been back 2 times to the Apple store. First time they said it was debris causing the crashes but that didn’t fix it. Second time they replaced graphics card b and the cables again. On the day I bring it home it crashes again.

I’m wondering if it’s worth calling Apple support even though I’m well out of warranty.
