I'm not entirely sure whats happening. My 6600GT SLI Investigation
mimics the results seen in that little article. AFR load balancing wont show any any movement other than a static line in 3dmark2k1.. I'm not entirely sure on this one. I'll do some tests myself as soon as I can with my 6600GTs without the bridge to see if I can get reproducable results. This wont be right away so please understand.
