Watched the vid... looks nice.  I have a similar setup with 2 Sapphire 5830's...

was wondering 2 things:

1. what is the gpu temp graph on the left that you are using... looks nice

2. Even with the config file mod I cant get afterburner to OC my clocks beyond the standard 875.... I have to use sapphire trixx, but that will only do the first card because they arent connected w crossfire cables.  im using the newest beta version of afterburner.  what version are you using? anything else im missing??  tia.
