Doctor Strange Is as Powerful as the Infinity Gauntlet

In the fourth episode of Marvel's What If...? Season 1, Doctor Strange pushes his ethics and skills to the limit to prevent the inevitable death of his girlfriend, Christine Palmer. To do that, he travels to the library of Cagliostro and learns of ways to obtain power through the Dark Arts. As a result, he is changed, and he inadvertently brings about the end of his entire reality. While the concept is terrifying to think about, it's even more frightening to consider that this reality's Strange could be equal to -- if not exceed -- the power of the Infinity Gauntlet.
