I'm starting to get more into peripherals and I want to upgrade my old G510. I see the new deal is mechanical keys (Cherry and Realforce) and I've seen everything from $100-$500 keyboards. What is a good median to spend and what are the top features I should look for? I actually made a chart and so far I have the k95, g710, Deathstalker, Quickfire, and a Ducky. Any help as to what I should look for (Gaming: FPS and MMORPG)
