My first build for gaming

Hey so this is going to be my first time building a pc and wanted to know what people think of the products that i have been looking at. 

beginning with the case: Fractial Design Define R4 Black Pearl

motherboard: Asus Sabertooth Z77

Prossesor: i7-3770k / i5-3570k

Ram: 16 gb of crucial ddr3 BallistiX Elite 1866 MHz (2x8) Can't find the link to the product

Graphics Card: EVGA GTX 780

Power supply: Corsair TX 750

SSD: Crucial M4 256GB

Extra hard drive will be added later. Also about the prossesor will the i5 bottle neck the build or be just ok, will gaming ever use the hyper threading? If I go for the i7 will it be like giving away an apple for free and then buy it back aka pointless for the build?

PS: I am not buying the products from amazon because the cost of importing it is to much.

It won't be a bottleneck at all . Gaming won't really use hyperthreading , so i'd get the i5 3570k , the i7 is only necessary if you're editing. The 780 is a good choice , not sure what the minimum power supply requirements are but you could save a bit of money and just get a 600w PSU instead of a 750w which is a little over kill.

only get a 750 w power supply if you think you might want to add a second graphics card later
