This isn't actually a big problem. Comparing to the current situation, Valve will just release their own hardware with a massive user base, and have that platform be the target spec for PC games. That is the stock Steam Box and Valve with developers will make sure all games run perfectly on that. All custom specs will be handled like they are now, expect now there is a single target spec everyone agrees on.
