Doesn't look like it.

What does disk caching have to do with smoothness of scrolling a small page up and down?

I guess I should run some experiments, like yank out the 6600GT card, or un-rotate the screens, or both. And try just one screen. There's just a huge (like 10x) perf loss natively. Gotta be something X11 related and the nvidia driver and my configuration.
