What is happeneing to my screen

I just got a much better gpu and now this is happening randomly in my game, whats going down?

Which GPU do you use (post your dxdiag)? Also make sure that you use the latest driver. Rendering Issue? Black spots on the screen - Rendering - Epic Developer Community Forums
