If you're still looking for advise, I would recommend MSI. I personally have the P67A-GD80 for my i7 and I can tell you it's one of the most stable boards I have had. I have it running with 16GB (4x4) Corsair Vengeance at 1600Mhz.
It's actually one of the few boards I've had that was plug and play and without any tweaks in the EFI/BIOS rock and rock solid. Right off the shelf it ran 24h memory tests (memtest86+) and a 24h stress test without failing, I hadn't changed a darn thing in the EFI/BIOS.
It was stable with default settings running an i7 on 4200mhz, no tweaks not even core voltage (800mhz overclock).
Link below shows my system running at 4,8Mhz stresstest, 24 hours no failures.

. I thought the manual was oke though but then again, I never need them so I don't pay much attention to them
.
Good luck with your purchase.
