Hi, this is the list of the purchased items from Amazon.it:
PCPartPicker part list

CPU Cooler: Corsair H80i v2 70.7 CFM Liquid CPU Cooler
Memory: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-3000 Memory
Storage: Corsair Force LE 480GB 2.5" Solid State Drive
Video Card: Asus GeForce GTX 1080 8GB ROG STRIX Video Card
Case: Corsair Carbide 400C ATX Mid Tower Case
Power Supply: Corsair RMx 650W 80+ Gold Certified Fully-Modular ATX Power Supply
Case Fan: Corsair Air Series AF120 White 52.2 CFM 120mm Fan
Case Fan: Corsair Air Series AF120 White 52.2 CFM 120mm Fan

I was 100% oriented on i5 6600k + GTX 1070 but..... I found on Amazon.it the GTX 1080 at less (!!!) and I instantly bought it (€461). Now I've got some questions:
- Is the i5 6600k enought for the new configuration or I've got to step up to i7?
- What atx-size Asus motherborad would you use?
- Is the RM650x enought for the GTX 1080 and the CPU that you picked?


The remaining budget (CPU and MOBO) is something like €400 (50-100€ more if it's really worth).
Thanks!

The items on the list have been already purchased and I spent something like €950. Now I've got €400 left for the CPU and the MOBO, maybe €450-500 if really worth.
The original idea was getting an i5 6600k and overclock it a little bit. Now, since I've got the GTX 1080, I'd like to have a CPU that is not underpowered if paired with the big 1080. And, If possible, using the 650W power supply that I already bought.
