1000Hz is enough to match CRT quality on a sample-and-hold display, but only when you're displaying 1000fps content. A great many games are limited to 60fps, which means you'll need to either interpolate motion, which adds latency and artifacts, or insert black frames (or better, black lines for a rolling scan, which avoids the latency penalty), which reduces brightness. Adding 16 black frames between every image frame is probably going to reduce brightness to unacceptable levels.
