currently using one now. all mechanical keyboard are good for gaming, its just the type of switches that make all the differences.
But if you into changing keycaps then quickfire tk is a no no. Well you can change most of it just that you can hardly find replacement for the bottom row keycaps(CTRL,ALT etc).

woah, long time no see
how is your taihao keycaps? still like brand new kah?

I also want to change my current keyboard. I always punch the wrong key and dont know why. No problem whatsoever when using notebook. Rosewill RK-9000 looks good. Is there any other that you all sifus here can recommend? Purpose is for gaming with internet browsing and microsoft office.
