Anti-aliasing is far too controversial these days and certainly doesn't deserve all of the discussion. In almost all cases, users end up preferring to run in high resolution versus anti-aliased since the performance impact is the same. I personally think that anti-aliasing is most useful for older titles that can't run at higher resolutions. I don't find myself playing those too often these days, though. What's king is balanced solutions that offer users current value today, but gives developers the ability to build the cool games of the future we crave.
Fill rate is important, because it does affect so many features.
The insanely high fill rate capabilities of the GeForce2 allowed us to really push forward per-pixel shading, for example. But with GeForce2 GTS, we're moving beyond fill rate. Word's out that you have a kick-ass gaming machine at home. Okay, hardware geek hat on. All of them have either GeForce DDR or GeForce2 boards.
