I was wondering if this would be a good gaming PC

CPU: Intel Core i7 4790k
CPU Cooler: Corsair Hydro Series Extreme Performance Liquid CPU Cooler H100i
Motherboard: Gigabyte GA-Z97X-UD3H-BK (Black Edition) Motherboard
Ram: Corsair Vengeance Pro Series 16GB
GPU: EVGA GTX980 CLASSIFIED ACX 2.0 4GB
PSU: EVGA SuperNOVA 750 G1 80+ GOLD
HDD: WD Green 2TB
SDD: Samsung 850 EVO 250GB

very good but i would go with a WD black drive instead of a green one
