Keep in mind that video games are optimizations on top of hacks on top of optimizations on top of hacks on... This is necessary, because we simply don't have the number-crunching capability to simulate the video game world better. If developers could have that horsepower, then they'd probably use it. In other words: as people get faster hardware video games will start using more computational power. This allows developers to scale back some optimizations and usually allows some different styles of games. Another thing to consider is that the number of pixels pushed to your screen is one thing. Another thing is that you will need higher quality assets with more detail too.
