SLI NVIDIA Surround issues

So against my better judgement and advice that I have given out many times, I bought another GTX 660 and three LCDs. Asking for trouble I know, but I had to try it out again. Here is the issue, so far, Black Ops 2 and Dishonored really don't run well. Other games run just fine. I am using widescreen fixer and setting the resolution to 5880*1080 with bezel correction. I see high frame rates and then they go really low at times and it stutters (120-20FPS). It runs fine with SLI on one screen as it maxes the FPS at 200 and never goes down. It doesn't seem to matter what the settings are either, low or high, it doesn't go away. Any assistance with this is greatly appreciated. Thanks.
