I bought a rx 560 not too long ago for my mothers old pc so she could do some work online and I was just going through her pc to see if it is working correctly because she told me it was kind of lagging and by going to task manager I quickly saw that her pc was recognizing the gpu as a rx 460 and not as a 560. what does this mean? the box that it came with is saying that the gpu is indeed a rx 560...
