The article text provided consists only of PC Gamer's website navigation, membership sign-up prompts and boilerplate content — the actual article body was not included, so no genuine summary can be produced. Based on the headline alone, the piece appears to be a first-person account of the author running a demanding GPU stress test that outperformed their usual gaming PC in some way, but the specific test used, the hardware involved and the results are not available in the supplied text.

Without the actual article content, it is not possible to responsibly report specific details, numbers or context. Please provide the full article text (rather than the page's navigation and sign-up elements) so an accurate summary can be generated.
