Ever since I installed the asus amd R9 280x TOP with Battlefield 4 in mind I have been experiencing graphical issues in the game.
Running three monitors with a 5040 x 1050 resolution.
AMD Cataclyst control center 13.12
It doesn't happen all the time but it seems to happen when there's a lot happening on the screen.

I figured it was because of Battlefield 4 with all it's bugs and that.. but I just played a game of Team Fortress 2 where it happened too thus worrying me.
It's not a lot of information to go on but I'm not SURE what to mention.

It's a mix of Green bars, old, classic static we all REMEMBER from the old TV's just randomly through the games,  in BF4 it's on all three monitors.. TF2 only supports 1 monitor so I can't say the same of this gameWhat are the REST of your system specs?  Has this ever happened on the desktop, or when playing a video, or basically at any time other than gaming?
Have you checked your temperatures?
These artifacts are often caused by EITHER overheating or bad graphics MEMORY (VRAM).  Drivers can also play a part, was this a new build or did you upgrade from another card?  If so, what card?
