Keyboard: Corsair K70 http://www.corsair.com/en-us/landing/k70-rgb
I have never considered replacing this, love it.
Mouse: Logitech G Pro http://gaming.logitech.com/en-us/product/pro-gaming-mouse
Just changed to this from the Logitech G502, this thing is amazing.
Just what I have, love my peripherals so far. I'm personally not a big fan of Razer's products, didn't like the ones I have used in the past.
