Love Linus also (no homo, haha) The build that they do make are awesome and future proof. But expensive, so if you are not really into overclocking just tell us so we can suggest a cheaper and better build or maybe not better but same performance for a cheaper price and still stable.
660 or 680? Depends on what you are using it for. I game on one 1080p and crank up the settings and get 60fps with a 660ti, so it is enough for my setup. You are spending a lot on your build. If I were gaming I'd drop the 3770k down to 3570k cuz in gaming there is no real difference. However, if you do a lot of editing then I could justify the i7; but gamers buy i5s cuz it is plenty.
Second, 8gb of RAM is enough. I never exceed 5gb in games. If you do editing work then 16gb is better but 8gb should suffice for mild work.
For gaming (real fast, 2ms) Asus monitors are a good buy, however they are TN panels. If you want a good all around monitor (speed and color) then look for 5ms IPS monitors.
