I'm currently saving my pennies for a new Mac Pro and a 24inch ACD. For owners who game, is the ACD's 14-second response time a problem? Is there a lot of noticeable ghosting? I play mostly fps's (CS:S, Day of Defeat, CoD, etc...) so this is a big issue for me. I'm dead set on the LED ACD so this is the only potential issue that's might hold me back. Thanks!
