Thanks a lot for your answer!

It's probably safe to say that everyone is working on what you would like them to be working on, including a few things you haven't thought to ask for yet
My point was more like: there's a lot of stuff now that could be worked on in the open as it should not involve much/any IP. What I mean typically are the GL functions to support and optimisations. IMHO those should not be worked on secretly and then thrown out like how it was with UVD.

If you want an AMD APU based machine right now under Mesa, a 5800 or 6800k is definitely a better buy. Just like how a 6970 still beats any SI card under Mesa.
Though I do know it took Mesa 10 and kernel 3.12 for the hdmi audio to work, and it still doesn't resume the hdmi output if I suspend it.
* like this one https://teksyndicate.com/videos/buil...c-nov-dec-2012 or https://teksyndicate.com/videos/buil...sole-build-one
** except the need to downgrade Xorg and kernel on latest linux distributions due to AMD not keeping up
What non-AMD solution would you guys recommend for a low-cost linux gaming PC equivalent to at least AMD A10-6800K?

Remember the old days when Linux was the only OS to support fully and natively AMD64?
I shaw this benchmark result about HSAHTML Code:http://www.extremetech.com/computing/174632-amd-kaveri-a10-7850k-and-a8-7600-review-was-it-worth-the-wait-for-the-first-true-heterogeneous-chip/5
Considering the fact that Linux community can update the compilers to build binaries with HSA enabled quite easily compared to proprietary aging compilers and as a result binaries windows have and get the image...
Now for the GPU performance of RadeonSI driver I say let's wait for proper DPM to come and then recheck but it is a loss in the article that Michael didn't mentioned the DPM lack or didn't investigate it before post the results.

Michael always used "defaults" so i guess Kaveri run at static PM.
In unigine-tests my HD7770(radeonsi) has ~70-90% performance of catalyst.

Out of curiosity, how would AMD A10-7850K stack up against an AMD ATHLON II X4 750 FM2 + GF 640 performance-wise? The APU is more expensive here! I assume you meant something like EVGA GeForce GT 640 2048MB.
I guess APU-s are better bang for the buck only when you want a sub-$400 or even sub-350$ gaming system...

But its hard to compete with, say, a 260x + Athlon 750. They cost about the same, but the discrete gpu will do a lot better (I think, I know the 260x is a newer chip that might not have good Mesa supportl like the 7770 or 7850 around it).

Stepping down from the A10-7850K to the A10-7700 incurs a drop from 512 shaders to 384 shaders. Which, if you OC the ram for increased memory bandwidth makes a pretty large difference as in both cases the GPU is still running at 720Mhz.
