Upgrades: Headset/Keyboard

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

A friend of mine uses the Steel Series V2 siberia headset and im planning on getting one myself. They have them in a ton of colors and it is one of the most comfortable headsets I have ever worn (my buddy let me try his on and use it for a while). I believe Logan also owns/uses one.

As for the keyboard, i owned the Razer Black Widow 2013 for a while and i liked the blues but they where a bit too loud and always came through my mic and annoyed people. I upgraded to the G710+ and i was a complete upgrade. The browns have a great feel and it has a whole bunch of great features. Solid combo of headset and keyboard that isn't all that expensive.

I appreciate the reply, shifting my eyes towards the G710 and SSv2
