So to recap, both were right. I ran Furmark and it quickly showed me what was going on. Top card was overheating (climbing) once an intensive game was started. I've since bought some more case fans to help with cooling and now my cards are staying around 60 C. BF3 seems to work good, only problem I have now is I will occasionally see Green and Red screen flickers when playing. I haven't driven back the drivers to the manufacturers drivers, I'm running off of Nvidia's latest drivers. I think this might have something to do with it... but just enjoying my time playing.
