I might sound lame, but why spend money on peripherals when you can spend that much on upgrading the components which will actually run the game? I've got a cheap MS 200 Wired Bundle and it works perfect! In my opinion, mechanical keyboards and high dpi mice are really just a gimmick. My rubber dome keyboard feels and sounds like a mechanical one and my mouse is more than good for my gaming needs (I play games like BF4 and COD Ghosts). I'd suggest buying the one which satisfies your needs and upgrade the components. However, this is just my view...
