Try updating your drivers, lower your overall resolution see if that helps any, turn your overall graphics setting down. shader,texture,etc.
I run an AMD 8 core, 2-AMD R9 280x, 16 gigs ram, on a 42in Samsung 1080p 3D TV and run game fine on max settings with no issues. All drivers for motherboard and cards updated,etc
I'd try lowering the overall graphics quality to see if that helps.
