R9 2xx series driver improvements.

Is it possible that all new drivers only give benefits in games only for Polaris but dont take any account on r9 3xx and 2xx gpus? i have a r9 290 and i dont even find a reason to update amd drivers because in the notes i dont see anything related to it and possible improvements to recent games. its still a GCN uarch, and a powerful gpu with more rops and tmus than a rx580, but still it seems not fully topped on its functions (maybe only my opinion).

Even tho i OC to 1150mhz, still dont seems to catch up with its uarch to rx580, wich gets more and more gap every patch.

We will ever have an all round final driver around old r9 series? Or these are already in Legacy? Honestly i just think that since both (rx580 and r9 2-3xx) are GCN, they can still juice up game performances on old cards.
