I'm not sure if it's still the case but even in cheap keyboards if you pay a bit more you they will have better controller that will let you press more keys at once which is important for gaming. I got my mechanical keyboard couple years ago and overnight I stopped making so many typos and I can type much faster. My plan was to check the keyboard out for a week, write a ton of documentation for work and send it back but now I don't regret paying extra for it, in fact I think it's the second most important component of you computer after the fastest hard drive you can get.
