There's no flicker on an LCD @ 60Hz. That's just the image feed rate from the machine.
Should make for smoother movement though, for sure. But flicker doesn't happen on an LCD with DVI connection so you shouldn't be having eye strain.
Will find out for you about the availability of this for you. Sometimes the suppliers here just will not bring in the good stuff.

And ja, most likely going to robbed of R5K for the thing if they do bring it in. The one I'm after is R6K as well and it only offers the max 60Hz as defined by the single DVI connection standard.
Will get back to a little later this morning.
