I checked the BIOS there is no information on GPU there.
My computer is this one:
custom gaming laptops - Welcome to Sager Notebooks
I got the Geforce 980M + 32Gb RAM + SSD. Windows 8 PRO (64 bit)
I Use a 3D software that uses the GPU to help calculation (CUDA). Even though i go to OPTIMUS SETTINGS and select both global and the 3D program to use the HIGH PERFORMANCE NVIDIA card
the software insists on using both cards and so it crashes. I have another notebook with an earlier card (geforce 560M with a sandy bridge model) and there was no INTEL Graphics HD there. But now all the processors have this card?
