I have a 23" NEC IPS display and the nvidia 9800 gt video card. Even when I enable vsync in flash and games, I still get tearing--a line in the middle of the screen every few seconds or so.
Is the video card or the diplay causing the tearing? Would ugprading to a better video card, such as the nvidia gtx 650, fix the problem?
Issue occurs on both windows and ubuntu; currently running the latest Ubuntu with the latest nvidia driver version 310.
