Graphics tearing(not sure what to call it)

This only happens with some games and I'm not really sure what it is or if it just happens but when playing certain games, jagged tears sort of just dance across the screen when moving around or in certain cutscenes. Not sure how else to explain it. The more I move around the more it happens but if I hold still then it doesn't happen at all. I'm using a gigabyte 7870. Not a huge issue, just annoying

try turning vsync on. but it sets your framerates to that of your display.

 

I usually have it on and it doesn't seem to make a difference on or off ):

unstable overclock? what are your temps? drivers updated?

No OC. Temps about 21C. Drivers all updated. So far the games it happens with is Amnesia, Alan Wake, and occasionally Legend of Grimrock.

Have you tried messing with the settings? (Resolution, AA, etc.)? Do those games have anyhting noticable in common besides the tearing? is your directX updated? Are those games trying to use PhysX?
