The 890GPA-UD3H is an okay board. I actually was expecting more from it, but I was a little disappointed. The layout was not that great and needs to be re-thought in future models. I am not sure why they continue to put the x1 slot up and over the NB heatsink, but they still are doing this.
There were a few performance issues that I did not understand with the 890GPA either. We saw decreased performance almost across the board when we have a discrete GPU in the system. I would not have expected this at all and we are working to try and find out the reasons behind this problem. As noted, there were some minor annoying problems at startup as well, but nothing too serious.
Overall, the GA-890GPA-UD3H is not a bad board, especially with its $140 price tag, but GIGABYTE has some work ahead of it to optimize the BIOS so that some of the issues we saw are lessened or removed completely. However, at the time of this writing we really cannot recommend it if you are interested in the 890GX chipset.
