On previous reviews here, (not only on 290X but 780s as comparison), with same 3570 at 4.2Ghz,
2,560 x 1,600, 4x AA 16x AF, ultra detail settings, DirectX 11
The 290X (normal???) with Cat 13.11 was Minimum 36, Avg 44.
Now on "Uber" mode with Cat 14.1
2,560 x 1,440, Ultra Detail (no description about AF & AA though)
Min 40 Avg 48.
I doubt 4AA, 16AF and 410,000 pixels can provide only 10% hit. Or do we miss something from the settings used?
Other than that, great review proving that all these 45%-50% performance on graphics alone, was a "myth". Yes on the low end, but on overclocked i5 and i7 the gain is minimal. (hell my 4820K is at 5Ghz).

If they could get a quad channel memory controller onto the next APU it would show a massive performance improvement (at 1080p) even keeping everything else the same.
