The Website "Can You Run It?" keeps analyzing the wrong video card

hmm... 740m

would this happen to be a laptop or is it an AIO machine?

if its a laptop... run the benchmark when you have it plugged in. likely the system runs on the intel chip when not plugged in to save on battery use (this is the case with most laptops) unless you specifically have the power settings to do otherwise (at the expense of greatly increased battery use).
