My 15" RMBP has been crashing during graphics-intensive use such as 3D modelling & HD video playback... I clicked on system report, and it shows only the intel HD video card! Further, the laptop is passing all the "apple authorised service centre" hardware tests (I am in India and there are no Apple stores or genius bars). Help!? Also, could someone please post a screencap of their system report in the "Graphics/Displays" tab?
