Photoshop CS5 and 10 bit color space-

I'm currently using a 20-inch NEC 2070 NX (8 bit) monitor which calibrates nicely with Eye One Display 2 calibration. I was thinking of upgrading to a larger monitor. I see CS5 supports 10 bit color space. http://forums.adobe.com/message/2729835#2729835

Anyone using one of the 10 bit monitors? Thoughts? A waste of money for most of us?

You'll need not only 10bit monitor, but also professional video card, like nVidia Quadro or AMD FireGL.

Software drivers for consumer cards do not support 10bit color.
