Hm, nothing like running your own benches - great fun and all that - but ocaholic.ch do actually have performance ratings for all the Catalysts back 11.12 in their 12.9Beta article:
Seems that after a shaky start, AMD's driver team have been working really hard. Question is can they squeeze any more out of GCN or is this it? New drivers are due tomorrow so we'll see soon.
Yes i did include that url originally in the OP.
However i decided to run some of my own tests as well.

The new drivers are indeed due tomorrow and if you read my post above the AMD rep indicates more gains on the way for battlefield 3.
Can't wait.
