This is my hardware below. I also have the same set up except using the A-8 5600K CPU on another system with out any problems although different memory. They both are running LM 14 Mate
G.SKILL F3-14900CL9D-8GBSR Sniper SE 8GB
LG 50" Plasma.
So I tried both the Catalyst 12.10 and 12.11 with the exact results. What happens is when I open up any 3d game I get lot of video flickering/flaring. I've posted a video of it with Open Arena. When using STEAM under Wine and Company Of Heroes the effects are so bad you can't play the game. If I run glxgears there's some flickering in the top blue gear.
This doesn't happen with the radeon drivers but I have other non video (HDMI sound) issues with those.http://www.youtube.com/watch?v=yzEWxErH ... e=youtu.be
