Just installed a second GTX 680 and having issues. I get what looks like major screen tearing, whether vsync is on or off. I get black bars, mostly appearing on the bottom of the screen. And it just looks like the screen is vibrating if that makes sense. This only happens in game.

I've tried both cards just by themselves without issue. My case is well ventilated. I've tried different driver versions.

The artifacting does not show up when I take a screen shot.

My PSU is 1000 watts but could it be a power issue? Maybe the SLI bridge?

Thanks in advance....this is driving me nuts!!!
