I'm pretty happy with my Logitech G15 and G510 keyboards, however I just picked up Battlefield and SWTOR and I noticed I'm getting some slight hand fatigue from mashing the buttons. Do mechanical keyboards help remedy this? Does it really make the gaming experience that much easier? Is it a night and day difference? Was looking at the Corsair K90 if I were to pick one up because of the Wrist rest and the lighting with the multi-media functions on it as well.
