Ok, I've renew my list:
CPU: Intel Core i5-4690k 3.5GHz 6MB Sk1150 - 249,90 € (I'll try to learn how to overclock )
Motherboard: MSI Z97-GD65 GAMING - 170,90 € (or the GAMING 5, I've chosen this one on looks because it was only 10€ more than the Gaming 5)
GPU: Asus STRIX-GTX970 - 399,90 € ( The GTX 980 is almost 300€ more than the 970. I could buy a second 970 for that )
Ram: Gskill Ripjaws DDR3-1866MHz 8GB - 59,90 € (I wanted a trusted brand, so)
CPU cooler: WC Corsair Hydro Series H75 - 89,90 € (I wanted to maintain the water cooling because of looks, so I went with a smaller one from a known brand. Do you think this works with the overclocked CPU? )
Power:Corsair RM750W - 146,90 €
SSD: SSSD Samsung 2.5" 850 Evo 250GB - 129,90 €
SATA: Western Digital Green 1TB SATA III 64MB - 60,90 €
Total: 908.3€

Asus R9 390X-DC2-8GD5 - 509,90 €
MSI R9 390X Gaming 8GB - 499,90 €

So, the question, How do you think a machine like this will handle GTA V for example?
