I've ran a single 670 for the last few years. Recently, I got another 670 - used. They're now in SLI, and it definitely increased my FPS - it was a decent investment.
However, now: my 3 monitors randomly (usually or perhaps only when I'm on my desktop; I don't recall it doing this during a game, but it may have) distort/glitch/tear.. not sure how to explain it. There are horizontal streaks that appear and disappear very quickly. I think it looks kind of like the error/static you'd get when you had a poor analog connection, or a digital connection that was coming loose. It's also not across the entire area of the screens, it's just part of.
Any ideas why this happens?
