That's what im thinking to do
I got 300$ laying around dunno what to do with them
Definitely go for the Corsair (K70 or K95 RGB). If you go for a keyboard with prettier colours than the practicality you want e.g. the heaviness, you're gonna regret it like me. Besides, the Corsair K95 RGB has awesome colours too, maybe not as much as the chroma but definitely awesome enough. It's probably also more sturdy. All in all, Corsair's the way to go.
My donnies, I would appreciate if you if I helped and if you think I am reputable.
