I thought I'd pop in here and give a little input.
I'm one of the gamers that "ride the actuation point" as someone put it. In fact I do it so close I have problems with the Cherry MX black switches... When you just dip down to the actuation point then back up on them, they sometimes register the key twice. This of course can be very bad lol. MX blues are the worst, since if you don't bring your fingers back up high enough, it won't listen when you press the key down again.
Anyways, I use the 55g realforce, and it is the best keyboard for gaming I have found yet. Double pressing the keys work quite well, and they also work great for either full bottom out or just dipping into the actuation point. I really don't have anything bad to say about the realforce, except that I wish the keys were perhaps a little lighter. It did take me about 2 weeks to get used to gaming with it, so don't return the board the next day if you get it and it seems weird to game or type on at first.
