I've heard a few people say this. Can I ask where did you hear and do you have any benchmark locations?You won't go far wrong with the items you have listed for your upgrade. Only suggestion I have is to swap the memory for 4 sticks of 8MB each - the old mantra that 2 sticks of RAM is best has been stood on its head by the new generation of Ryzen processors which generally give better results (ie FPS) when running on 4 sticks of memory.
Good luck.
