Although not officially announced at E3, Saitek's latest Cyborg Rumble gamepad for the PC takes the best of the Xbox 360 controller and enhances it with some FPS-friendly features. First off, there's a precision control toggle, which when activated, turns down the sensitivity on the sticks so you can go in for a headshot easier. If this sounds familiar, that's because the Splitfish FragFX controller does the same thing, except for the PS3. And then there's the Xbox 360-like design, which is perfect for all the ports of Xbox 360 games heading to Games for Windows this year.

The only thing that sucks is that the thumb sticks are too close to eachother making it a problem with comfort and controll.
