Basically a CRC monitor uses analogue technology and refresh faster, TFT's use digital technology but refresh slower. The extra sharpness with TFT's makes motion slightly strobing - like with CRC's things blend smoothly, but with TFT's it does'nt blur in the same way. For example, a white dot moving on a CRC would look like it had a trail - but on a TFT the blurring is left pretty much to your own eyes, which don't update very quickly at all.
If 'they' had convincing motion blur in games, they could run at 25fps and it'd look smooth as silk on any display.
