I'm looking to make a gaming PC and here are the specs & the case.
NZXT Phantom 820 Case
Asus Rampage IV Black Edition
Intel Core i7-4930K 3.4GHz Socket 2011 Hexa Core
Samsung 840 EVO Basic 2.5" 500GB SSD
Seagate 7200.14 3TB SATA III 3.5" Hard Drive
Corsair RM1000 1000W Power Supply
Corsair Vengeance Red 16GB DDR3 2133MHz Quad-Channel RAM
But... for the graphics card do I get two Palit NVIDIA GeForce GTX 760 4GB Jetstream Edition
Or... one EVGA GeForce GTX 770 Superclocked with ACX Cooler 4GB Graphics Card until I can afford to purchase two.
That CPU is overkill. Stick with an i7 4770k or an i5 4670k, because the CPU isn't used that much when gaming. You don't need 1000 watts, nor do you need 16GB of RAM, and you probably don't need that high end of a motherboard either. I'm just looking to save you some money, because for gaming, half of what you have is complete overkill.
You need to spend the majority of your money on the GPU.
