Questions about return

[omenatarhuri]

can you post proof please because yours is the first case I've heard of this.

I was reading the comments section at Arstechnica review. The author ran a stress test and found the GPU hitting 105 degrees. At that point it apparently throttles, but keeps running (instead of shutting down).

The stress test is very tough to be fair. 100% GPU and CPU. This most likely is not the case in normal use/gaming. The fan was 3200rpm at that point.

No, other people are reporting that the GPU is running at high 90s-low 100s C at normal load for gaming on the Retina iMac. This is above the reported upper limits on GPUs at the moment, especially ones that are embedded on the motherboard. I'm just… shall we say… less willing to be a test case for an issue I think will be a discussion point down the road.

I'm still an enormous fan of the Retina iMac, but I spend most of my time on my home computer gaming, as opposed to doing other things like web browsing.

I prefer OSX to Windows for general use. But I wouldn't play games on OSX. I said it before, I feel DirectX > OpenGL.

I used to have a dedicated gaming PC but eventually just went with bootcamp Win 7 for the convenience. Older iMac was a base mid-2011 27" with a 6770 Radeon 512MB VRAM.

Now is a top-end 5K with m295X 4GB VRAM. Still... gaming under OS X is not ideal. So it's bootcamp for this machine as well. Here's my post in another thread.

Anyway, I have been playing Civ:Beyond Earth, Dota2, Heroes of Newerth, CS:GO, L4D, Tomb Raider and Shadows of Mordor on full settings and all at 2560x1440.

I tried 3840x2160 (the max that Win7 lets me) on a couple of games and it was less than ideal

No, because as I indicated before, I returned mine the day after, when I couldn't get my iStat to show GPU Die temps below 100º C while running World of Warcraft and Guild Wars 2 at 1440p resolution. I'm telling you what *my* experience was running this.

And as far as aggri1's comment: http://9to5mac.com/2014/10/28/apple-class-action-lawsuit-2011-macbook-pro-gpu-graphics-issues/

Yeah the MBP situation is unsettling, but perhaps you had a faulty unit?
