^ I would go for the Microsoft X4. or the X6 even (if you like having tons of macros for your left hand).
Those are in my opinion, the best bang for buck keyboards. The x6 has an interchangeable num pad which you can move to the left to allow for like 30 macros IIRC, on the left. Or the X4, which is great. And the macros do work quite well.
And they are decently backlit. Not immensely bright during the day, but you can see the subtle lighting, and decently bright without blinding you from the screen at night.
EDIT: I forgot to ask you sth. What do you look for in a gaming keyboard? Ask yourself that, do you use tons of macros and stuff? And do you need LCD screens? Cos I came from a Microsoft X6 with tons of macros to a no-nonsense mechanical Filco Brown Keyboard and I found myself getting more gaming performace, as I didnt use the Macros on the X6 at all.
For a gaming keyboard, I recommend the CoolerMaster Storm Quickfire Rapid tbh. And I use the program Sharkeys to disable the Windows Key, and use the PageUp and Page Down keys to change the volume and the Scroll Lock button as a Mute button. I highly recommend this program. It doesnt even have a toolbar logo and will automatically turn on the key changes everytime you enter Windows.
