Just to tell you the truth other than the LED options nothing all marketing ploys with a twist of words. Corsair has been known to have the same exact keyboard and then rename it with the word Gaming in it to make you think you have something special when it's the exact keyboard.
My experience with Corsair keyboards, bought one, sent it in for warranty 3 times in a 8 month period for the keys randomly not responding, long story short I smashed that crap in the street in front of my house and left it their and that really felt good. Your experience could be different.
If your going to spend that much for a keyboard look at Ducky.
