Nope, since graphics cards go hand in hand with user experience. Not everyone can buy a TitanXp, but they still want a good experience.
It's the reason we have graphics settings after all. You tweak it to find your sweet spot between performance and visuals.
If you can gain 50% increase in performance, for a nearly unnoticeable drop in visual quality, many would take it. Even more so if the same setting ( DoW3 AA at High ), reduces the overall visual quality; which for many also reduces their enjoyment.
You might want every slider, and setting maxed out, even if in some extreme cases it'll make the game look worse, and run worse; or barely add a noticeable difference; but other's don't feel that way.
They're still people that would be interested in a graphics card that fits their budget.
@JediFragger seems to be one of those; he wants the sweet spot of visuals, performance, and gameplay.
