well, i bought a gtx 650 ti boost a week ago and from the very 1st day, after installing the driver i'm having some lines, very negligible moving lines on my display. sometimes the border of an icon moves downwards too, and it stops sometimes after and then again starts. but its so much little that one cant even see before going too close of the display or staring constantly at one single point. it isn't bothering me but just wanted to make sure if the cause is a faulty card. i use a dvi to vga adapter and 60Hz ref rate. games run pretty okay and gives desirable graphics and frame rates.
