Getting a new PC, need help

I am getting a new PC and because I am not very knowlegeable about it I would need some help in picking parts. I want to buy all of the parts in one store in my country. These are the possible stores:

I want the PC to be able to play games that are to be released in the following 5 years maxed at 60 FPS, 1080p.

The budget is 1500-2000 euro.

For CPU I was thinking about Intel Core i7 4790K.

For GPU I was thinking GTX 780 Ti.

16GB RAM, 3TB HDD, 256GB SSD.

I have no idea what motherboard, power supply, case, cooling I should take or what I should look at. I also dont know what version of GPU, RAM, harddrive to pick.

Hello.

I created one build for 1500-2000. I also placed an OS. Remove it if you don't want it.

You can add or remove anything you want, but more or less these are what you should aiming for.

I don't know if the other companies are cheaper though...

edit: I just added 3TB HDD and 16GB RAM, if this is for gaming, both are useless at the moment...

lower mobo save some money , Dont need a $740 gpu.... for much as you pay you can go through 2 two gpu upgrades and actually gain something when you upgrade

Gigabyte GA-Z97X-SLI

You can pick up a overclocked GTX 780 for almost half of a 780ti, and your only losing 15% on average performance.

Yeah ofcourse. You can get like 80-90% of the gaming performance with almost half money...

I just created a system that op asked...

Games maxed for the next 5 years: i5 4690K, 2x 290 or 780 (not the Ti version nore the X), 8-16Gb of RAM (I'd pick 8 now and add 8 more later IF needed), for CPU cooling Corsair H100i or Noctua D14, 1Tb Caviar Black, 850-1000Watt PSU, any SSD at the size you can afford (if needed at all).
