Summary: I bought one about 2 weeks ago. Have had random instability. Started swapping parts two days ago, trying to isolate the bad component. Ruled out everything but this motherboard and the CPU in it. Bought a new motherboard today, so I'll know for certain - but I'm 99% sure the 870A I got has issues. Seems like it would be a pretty great mobo otherwise. I'll revise this once I'm sure. Bonus - we get to see how Amazon is with returns! Whee!
Summary: got this board to run as a high end file server. First major issue I realized (after building it of course) was that it has absolutely NO MONITOR CONNECTION. No, dvi, vga - nothing. The previous 2 Gigabyte boards I bought both had so I just assumed this would too, bear that in mind when you purchase it as you will need to get a graphics card also.
