Provided the refresh rate on the LED monitors is still somewhere below 10ms, you should be fine. The major benefit of the new LED monitors is the improved color accuracy and black level that comes hand in hand with being able to independently light and dim individual LEDs. It's really a big difference and goes a long way to improving the quality of an image or game. However, if you aren't too anal about color accuracy and black level you might as well buy a cheaper monitor.
