My brother has an A6-6400k paired with a MSI A78m-E45, R7 260x i believe and 8gb of RAM. Now he plays COD on PS4 and streams through his elgato to twitch but says the video is choppy like the computer can't keep up. So i suggested getting an X4-860k because he doesn't want to change his motherboard from the FM2+ socket. Any suggestions appreciated! I think with the +2 cores he should notice a good difference in the computers capability. He doesn't game at all on the PC but will be using it for video editing and streaming.
