Ok, so last night I was tired as hell when I wrote the post, I just woke up and I tested both cards by them selves and they work individually NP, so I it's not the cards fault, I did the guru driver sweeper it kept freezing on me so I manually uninstalled all the drivers and also the registry, opened in safe mode, ran the driver sweeper again, success, re-installed same thing, mass tearing and no focus, turn sli off and it works with one gpu, I am completely new to SLI so I don't know anything about how to check witch SLI mode it's in, so please bear with me and treat me like a child when it comes to sli.
Are you using the drivers from the CD's? Did you use the latest Nvidia drivers? Also maybe its the bottom PCI-e slot (I doubt it but its worth a try), try BOTH cards in the bottom slot and see if the problem replicates.
Also, maybe Mousemonkey can debunk this, but I've never heard of that PSU brand so it COULD be the PSU. Reviews of it look good though.
