Look at gpu's. As the core counts go up on them. They keep simultaneously forcing higher and higher resolution screens. Because they can't improve performance much on normal resolution screens but they can give the gpu's more to do on each frame.
Computer manufactures are stuck in 2 strategies. Doing what is feasible and workable and hoping it's accepted by buyers. Or working towards nearly unachievable goals and simply lying about progress as they go with customers buying and giving a son i'm dissapoint reaction at every stage of it. So it's either 2560x1600 3d screens that give you headaches or nihilism and converting your early adopter groups into wait and see groups over time.
The problem is they went many cores to get around the clock speed problem. Now they need clock speed to get around the many cores problem because only speed will bring the busses out of lock out faster. So you need what you can't get to fix what you got but can't get.
