We liked the ASRock 870 Extreme3. It is fast, clean, easy to use and only $89.99 from NewEgg.com. At this price you can probably grab more RAM, a better GPU, or even pay for the full versions of the trail software included.
Our gaming experience was also great, but our overclocking experience was not that great. We are pretty sure that ASRock will correct this with a future BIOS; after all, they did put a ton of overclocking tools into the current one. We did not get a chance to try out the Core Unlocker function, as that is for another article, but it can also lower your overall cost if you can pick up a tri or dual core CPU and kick it up to a quad.
We think that this board could be one of the best AMD based motherboards in terms of bang for the buck that we have tested.
