I second i7baby. Everything's OK, and with a 770 you'll get around 45-60 fps with AAA games on high-max settings @1080p. I too would get an i5 cooled by a 212 evo although, and unless you're into overclocking, I'd get the non-k version to save those extra 20 bucks. Get a 780/780ti for better future-proofing, and although the 650w is fine, I'd get a 700w just for the ease of mind.
As per peripherals, Razer is like Apple: quality products overpriced to the max...
Some Steelseries, CM Storm or Roccat pieces, to name something I tried myself, usually have the same quality while costing a bit less. Played a couple games with the pieces you posted off a friend and played the same with my Roccat ARVO keyboard and my Steelseries Sensei RAW mouse. No noticeable difference.
