You know.. What i am going to tell you will not sound good. My board was Sabertooth 990-fx R2. My little story is that at first it seemed to run ok (with r9 270X card). I sinked enough hours to titanfall and it was great. After good period of time of non-usage (as board was in warranty service and eventually swapped to brand new board), multiple kernel updates and migration to archlinux i no longer could get it running as fast. Now i do not know if i just did not feel slowness initially and it was always there or if something changed, but i know for a fact that testing older kernel releases did yield a little bit better performance (enough that i could notice). So i moved back to dual-booting due to performance reasons. In the end combination of this and r9 270X constantly causing entire PC to go down with a red screen i simply swapped hardware for intel x99 + nvidia gpu. Such is sad story of mine..
