A few things lead to this including the obvious tablet/mobile disruption. PC Gaming decline due to console gaming and mobile and Moore's law and processor speed. I used to update for gaming and 3d almost entirely. I also used to update more frequently for processor speed/memory that were major improvements. If we were getting huge memory advances or processor speeds still there would be more reason to upgrade. Mobile is also somewhat of a reset and doing the same rise now.
