Is there a way you can snap a SS? I doubt it, but its worth to ask.

Have you overclocked your dual GFX card thing? Artifacts usually signal that you have overclocked too much or/and you have inappropriate cooling.

or that your cards arn't getting enough power for some reason. Im betting on the overheating cause though, since you have a 580W psu

It depends what brand the PSU is, some noname PSUs are pretty unstable and never have enough power, no matter how much watts.
Try opening your casing to let more air into it, it may help if overheating is the problem.
