Agree and agree

Particularly with the "subjective" aspect -- I go by what I "see" and "feel". If a consistent 15FPS minimum looks and feels good, its okay with me -- I won't measure the FPS (like I used to do). Others have different criteria and may be appalled to get "only" 30FPS -- even if they can't actually see the difference between 30 and 60 in a blind test. To each his/her own.

So, different folks may see it differently. I'll be interested to actually own an RX-480 and "see" and "feel" what it gives me. I am open to the possibility that it will have an unexpected flaw.

Regarding games, lately I play Fallout 4 (with some substantial visual mods that add loads of extra grass, plants, trees, and details) and Witcher 3 stock with updates -- both at maximum visual settings (0AA). Other games I play are not as tough on the GPU.
