okay peeps.
if you got titan x, 980ti, 980, or 970 this card isn't for you.
however if you are building a brand new system, and you want uncompromised 1080p on ultra, or 1440 on high. this card is for you. at $200 you can't go wrong.
if you are running lets say any GTX 700, 600, 500... series card, and you want to upgrade. this is more powerful than your card while being more efficient.
believe it or not people don't upgrade their GPUs every generation. I am running R9 280X that is technically a card from 2012. and i am perfectly happy with it.
RX480 is NOT a flagship Card, it is budget oriented for the mainstream users that make up 85% of pc gamers. people who don't really care for ultra settings at high fps and resolution.
Upcoming cards:
-RX490 Rumored to be dual polaris 10 on a single card. price range 400-500, should sit between GTX 1070-1080. ( high end aimed at enthusiasts). coming late this year.
-Vega 10: a very large die 16-18 billion transistor. Rumored to have double Polaris shaders, a new architecture (Gen9 vs Polaris Gen8). HBM2 for 1TB/s memory bandwidth. this card will battle the 1080s, 1080Tis the top dogs of nvidia. coming early next year.
Finally this is the latest 3Dmark DX12 benchmark. I chose this so no say it is biased.
