£50 pound is less than £200 aswell i think if you are going down this road you need to be going along this line of thought the best bang for buck card is the cheapest gpu you can fit which is say a gtx 750 or a amd 260 something?
Except as stated most reviews get different Fps from other reviews let alone in different games than run better on one side or the other and at different resolutions,
EG 290x often seem to pass the 900series at 4k but not at lower resolutions as much
BFB has to take the end user into account simple fact.

So what your saying is because the 900 series has way more features that your dividing into the price its BFB goes up. And ofc its a flat rate per feature
I see we get nowhere and its a waste of time so i will simply agree to disagree with you
May you have a good day
