I'm starting to struggle with that motherboard would be a good match for an A10-7850K.
It seems the Gigabyte A88XN-WIFI has some issues, and the Gigabyte A88X Sniper uses a lot more power than other boards (could this be a bios issue?), and the Asus boards available at the moment are a bit lacking.
Maybe waiting for the MSI A88X-G45 GAMING motherboards is the best idea. (not sure how decent/good/bad MSI boards are these days though)
The best current ITX board is the Gigabyte, on the new bios it's highly overclockable and keeps up with full size boards.
It's only current limitations are
1. you can't clock memory beyond 2400mhz
2. to get those speeds you need ram with a DDR3 2400mhz XMP profile, it wont clock the likes of Samsung Green at anything over 1866 as it has a DDR3 1600 XMP profile.
In other words Manual memory overclocking is hampered by the ram you put in it and it's XMP profile.
3. You need to update the bios to get Kaveri working with an older FM2 APU. If you don't have one it's better to wait for a new batch of boards with updated bios.
The Asrock board is fine at lower clocks, but it has no VRM cooling and it will be the cause of throttling the overclocks before you're cooling does.
It also doesn't like manual memory overclocking and is tied to the XMP profile of the ram you put in.
mATX
Asus A88XM-PLUS works with Kaveri straight off, clocks like a demon and clocks memory no problem up to 2400mhz.
(no comment on Gigabyte mATX boards, not seen one discussed yet, Asrock again has no VRM cooling)
The best current full size boards are the Gigabyte GA-F2A88X-UP4 and the Asus A88X-PRO, hands down.
Gigabyte G1 Sniper and the Asrock Xtreme 6 don't hold a candle to the above boards.
That's all the boards I'd be interested in if I was building right now.
They are the best of what is currently available, hardly Enthusiast Grade I'd agree, but that's it for now.
The MSI Gaming series boards are looking to be the first (close to) 'Enthusiast Grade' boards out the gate, and I can't wait to see how they perform.
This from my perspective as an overclocker and gamer, I appreciate not everyone has the budget or see's value in high end components in lower end builds.
I've had AMD APU builds since Llano and I enjoy tweaking the platform and seeing what I can squeeze out of it.
You certainly don't need the best of everything to enjoy what Kaveri has to offer, but there's tangible gaming gains with fast ram and tweaking the iGPU.
For people who just want an everyday PC or HTPC and have no interest in playing games or overclocking, fast ram is of course pointless.
The last thing that's irking me is there is no current (or announced) mITX board with Displayport (mATX now has the MSI A88XM Gaming board with Displayport)
I game on the iGPU (tiny mITX system I play in bed) and if Freesync gets into monitors sometime soon, you're tied to the current ATX boards which do have it onboard (Gigabyte UP4, MSI A88X-G45 Gaming and Asus A88X-PRO) which leaves mITX fanatics (like me) currently locked out.
I hope the post gives you clearer picture.
