If you intend on saving some cash DO NOT GO WITH DDR4, The extra 500+ euro you spend isnt worth the 4 FPS perform,ance unless you intend on doing photo editing, video editing ect. 8GB 1600Mhz is just fine and you wont see more than a 2 or 3 FPS gain going from 8 to 16 to 32. The 970 only has 3.5 GB of usable VRAM not 4GB, I highly recomend getting the GTX 980 with a good cooler and overclocking it.
