MBPR: iGPU vs. dGPU (15" 2014)

[FuNGi]

I'm glad i found this article!

I recently purchased a loaded 15 inch mbp primarily for editing photos and I found the reduced battery life somewhat lackluster. I have not been able to find any benchmarks running Lightroom/Photoshop on iris pro vs 750M. Would the Iris Pro be sufficient for what I'm doing?

Also, what exactly happens if the GPU dies while under apple care? A few of you mentioned this issue turned your machines in $3000 bricks...

If the GPU dies under Applecare then Apple will fix it for you for free. Sometimes 2 or 3 times in a row! I've had this done on my wife's old 8600 (third repair resulted in a new machine, and my 2011 AMD which I then sold). We're both running the 750M now (my rMBP, her iMac). Fingers crossed that this chip's a winner...but we bought Applecare just in case.
