Single GPU configurations are better instead of going SLI from the start. So instead of 2 x 770 i'd recommend 1 x 780 so you can upgrade to another 780 later on when you find it necessary. (unless you want to run 8 monitors get the dual 770).
Put in a SSD for your OS. And a 1tb HDD for storage.
Also the PSU i've put in there should suffice for another 780 so you won't need to worry about that.
This will run everything @ ultra settings and good/solid fps in most newer games like BF4, Crysis 3 etc.
CPU: you will never need an i7, even for the extreme gaming build. an i5-4670k would be enough.
Cooler: Corsair H100i is a better cooler than antec
RAM: Better to buy two modules for dual channel capabilities.
Storage: an SSD will speed up your performance considerably.
GPU: Its not a good idea to start your build with a SLI. You will probably never need a SLI setup for a single monitor gaming if you can afford a better single GPU. Besides, a CF produces a lot of heat into the system which can be a problem too. Start your build with a 780Ti and later if you find that to be insufficient, add another later and do a SLI.
PSU: for a single 780ti 650W is enough. if you want to SLI later then you need around 950W. 750W is not sufficient for 770 SLI. you need at least 850W
Then i shall comment why i would/wouldn't pick some of those parts.
Also solid though the i7 4770K is better if you play games like BF4 & Crysis 3 because these game support more threads/cores. And it's also a bit of "futureproofing" for more games that are going to support the more threads/cores utility.
Though currently that i5 4670K is that sweet spot in price / performance ratio.
The CPU cooler doesn't really matter that much. The H110 will cool better though then the H100i because of the bigger rad surface.
In my oppinion a GTX780ti is a waste of money compared to the GTX780. The 780ti performs almost the same as a Titan hower the GTX780 is 5/10% less in performance but is $250 less then the ti and $500 less then the Titan. So the GTX780 is my favorite in price / performance.
