That psu isn't gong to come close to powering two of those cards. The 480 is an out dated power hog. For your budget you have too much money in your case and board, not to mention that RAM is over priced and unless you plan on using it for a hair comb it's going to impede any decent heat sink you plan on using. The 2600K is not only cheaper, it takes all of a few seconds to get it up and past that 2700K.
Look at a cheaper board like the Asrock z77 extreme4, combo it with the cpu or hard drive, find a cheaper case... Corsair 300R would be a good choice, cheaper RAM that doesn't have those tall cake cutter heat spreaders, a decent psu....look at the PC Power & Cooling 750w psu on amazon or even a decent 650w psu for two of those cards and go for the Gigabyte 7850 on superbiiz for $260 + free shipping or get it from newegg for the same price + $7 shipping.
