I use a 10$ Logitech keyboard works fine for all my online gaming after my fancy one broke and there is no noticeable difference. Get a laser mouse after that it is all fancy gimmicks like adjustable weights.
Mechanical keyboards aren't gimmicky and some people like myself can't stand light weight mice that can't fit my hand correctly. I have very noticeable improvement in gaming and enjoyment with a quality mouse and keyboard.
