I currently have a Razer Carcharias headset and Logitech G510 keyboard. Although both have performed to my standards for the time owning them, I feel it's time for change. Would it be worth it to upgrade to a Logitech G430? (As its only $54 atm). As for the keyboard, I've somewhat grown frustrated with the periodic bugginess of Logitech software (Occasionally at boot the LCD on the G510 shows only a frozen clock and no gaming profiles work). I'm also interested in mechanical keyboards and have been thinking about Corsair's K70, Razer's BWU, and CM quickfire. I recently demo'd a logitech G710 in a BestBuy and like the way MX Browns feel, although I have nothing against Blues, they just seem a little too loud.
Price Range for Headset: $50-100ish
Price Range for Keyboard: $70-120ish
