3570K is best bang for the buck, but if you have the money the 3770K could be helpful in a couple years if the consoles force better threaded games.
How high are you planning to OC? A $35 Evo can get you ~4.4GHz, a $75 Noctua DH-14 probably 4.6 or so. Looks like little bang for the buck on the 100i.
What does that really expensive mobo provide you that a $140 ASRock Extreme4 (or similar) doesn't? See this article: http://www.anandtech.com/show/6697/asrock-fatal1ty-x79-champion-and-x79-professional-review-from-a-gamer-to-gamers/11
2133 MHz ram will have no appreciable benefit over a set of 1600Mhz ram at the standard 9-9-9-24 timings.
Why two SSDs? Can just make a C: partition on the larger one.
Two 670s (or better yet two 7970s) are a better price/performance value. But, you didn't say how many monitors and what resolution. A single 670 maxes most things today at 1080 ultra (Crysis 3, Far Cry 3 are exceptions).
850W PSU is the max you need (really could go with a 750). Why Platinum? You'd have to run it under load for the better part of a day for many years to make up the price difference from Bronze (assuming you pay US-level prices for electricity - BUT it's worth it if you find it on a great sale).

Why would you want to write BR disks? Slow and expensive compared to an external HDD.
Just some food for thought.
