EchohcE :
If memory serves, the 1070 and the Fury trade blows. Unless the Fury's giving you trouble, or you just want less power draw, I'd wait a few months and see what Vega offers.
I wouldn't say they trade blows. The 1070 looks to be about 20% better than the Fury at both 1440p and 4K. Since the OP has an ultra wide 1440p monitor their resolution is somewhere between those too. The 1070 will be an improvement over the OP's Fury in the vast majority of games.
That being said, I'm not sure I personally would spend $400 for a 20% improvement. I like to see bigger gains than that from my upgrades. A 1080 would be a more noticeable upgrade for you. If you went with a 1080 you would be looking at an almost 40% improvement over the Fury. If the 1080 is out of your budget I would probably keep the Fury until we see AMD's new cards or maybe the 1100 series from Nvidia.
