Hey guys, I'm upgrading my GPU soon and I was hoping you could help me. I'm currently thinking between:

and

And I was wondering, since I play World of Warcraft: Legion mostly, which of these cards would provide a smooth playing on Ultra?

These are my current specs:

INTEL Core i5 4460 BOX, s. 1150, 3.2GHz, 6MB cache, GPU, Quad Core
ASROCK Z97 Anniversary, Intel Z97, DDR3, zvuk, G-LAN, S-ATA, PCI-E 3.0, USB 3.0, HDMI, ATX, s. 1150
Memory PC-14900, 8 GB, G.SKILL Sniper Series, F3-14900CL9D-8GBSR, DDR3 1866MHz, kit 2x4GB
Radeon HD 6950
SSD Kingston HyperX Fury 120GB
Windows 10 Pro 64-bit (10.0, build 10240)
PSU Scythe kamariki 750W

I can't help you with performance in a specific game, but the 470 is both newer and faster than the 380X so all else being equal that's the one to go for, some benchmarks of the Sapphire versions here:
