RX480 is not good.. HELP!

Just got MSI Armor RX 480 8gb card.. low frames. 50-70 fps, when my R7 360 was getting 80-90. Screen flickering too! What's the deal?? I've taken out card, updated drivers, re-installed windows.. no luck. Thought it was comparable and even better at times than GTX 1060. Which maxes out at 200 fps on my game of choice.


I was absolutely sure the card would max out at 200FPS on America's Army (my favorite game i play)

my 1060 6gb maxes out.

my r7 360 2gb gets better frame rates..

i dont understand.
