I prefer a wireless keyboard (Bluetooth) and a wired gaming mouse. I used an mx5500 but the mouse couldnt stand up to gaming, and noticed occasional shudder. Logitech did replace it though free of charge each time. But the G500 is nice for the price, and noticeable difference in FPS games etc. Never experienced any problems with the mx 5500 keyboard though. comboMouse
I got mine for half that price. Also people love Razor mice... I'm not a fan of the look and feel, but others swear by em.
One thing to note gaming keyboards are BS unless you like the key lay out.... There is no speed difference just LEDs under the keys. Like I said the claims are udder BS.
