Working with the ASRock 890GM Pro3, I was a little disappointed. I had thought that I would see more performance out of this board given the performance we have seen from other ASRock boards. The performance was not bad; it was actually about average for an 890GX based board. It is just that we have gotten used to seeing much more.
We have a feeling that the more creative layout may be the cause of some of the performance issues. ASRock would have had to make a much longer and complex tracing system to accomplish the layout we see here. This impacted the HDD and memory performance which in turn impacted the performance of other tests.
Of course you are still getting a decent board and only spending $117. You could pick this board up and with its higher wattage CPU support you could drop in a higher speed CPU, then a good add-in GPU. We just would not recommend it as a standalone system, unless you are just looking for basic 2D performance.
