First off, big ups to you for using the system builder template. Makes our job of giving advice pretty easy.
As for your build, here are my thoughts:
CPU: good choice
Is there a reason you are going with EVGA other than you are thinking of going with two 560Ti's? If it were me, I would go with something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
mainly for the UEFI bios and the fact I have had a pretty good history with using ASUS mobo's. Also saves you about $15ish from newegg over the EVGA.
PSU: It's up to you and your overclocking, but if it were me this is the PSU I would use. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Nothing worse than random system instability because your PSU just ain't cutting it. you can calculate your PSU requirements here: http://extreme.outervision.com/psucalculator.jsp but it is just a rough guide. Be careful to add on some capacitor ageing. If you want to keep your system for 2-3 years then crank it up to 30-40%. if you really wanna skimp then go the AX750 instead of the AX850.
HDD: any reason you want the caviar black and not just a green or blue drive? the green drives use a fair bit less power and are cheaper. only real reason for getting the black drive is if you plan to install your games on there, or any other performance task which you can't manage on your SSD. i recommend this if u want to just use it for storing media/files etc: http://www.newegg.com/Product/Product.aspx?Item=N82E168... Saves you 20-30 bucks.
MoBo / PSU - Mobo is excellent and has full 3 year warranty (unlike Asrock whose B3 boards have 2 years, Z68 boards only 1 year)
Cooler - outperforms units twice the price (Prolimatech Megahalems, Noctua DH-14)
GFX - At 1920 x 1200,m take the 900 MHz 560 ..... at 2560 x 1600, the 6950 2GB Frozr
Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:
same gpu for less because of free shipping at amazon
i switched over from an asus pro board to the extreme4 after i got 2 faulty asus p8p67 pro b3 boards.
case- i recommended the nzxt phantom
jack that psu is out of stock go with the corsair tx 750 v2
that hd is 5$ cheaper at amazon jack but i agree with the choice
corsair force 3 is released another ssd to try is the ocz solid 3 or the ocz agility 3 both are very close to the vertex 3's performance but less expensive
also stay with that dvd drive i posted earlier
