From my personal experience, GNOME or KDE seems to lag compared to windows XX. The apps themselves are often faster and more responsive, but the mous pointer, dragging of windows, etc. always lag. By lag I mean there is a delay much more perceptible on XFree86 than Windows.
I am very sensitive to delays and skips in visuals, this kind of stuff annoys me, as a screen with lower refresh than 85 hz annoys me. Some people won't notice the difference.
