You can visibly see and feel the delay on the Wacom Centiqs and they're 60 Hz.

You adjust but it's not as ideal as there's mild tendency to under/over draw. This is probably less of a problem for a whiteboard but for art, its more problematic.

That's probably due to input lag rather than refresh rates though. For non-TN screens, input lag (generally >30 ms) tends to dwarf refresh rate differences (16 ms vs 8 ms).
