Guru3D: "The word back from Smooth Creations was that this system had been used for three days at an NVIDIA event (had to be NVISION, we where there btw) yet somewhere down the line of shipping this product to us, an employee inserted a second card and apparently didn't match it up. You know, it is one of these things that can happen, for whatever reason he did not check to see if the cards would work together at all. Granted, at this price and build level that just may not happen. Considering we've never received or seen any similar complaints on the web regarding issues like these, we'll consider this was an isolated problem. Mistakes do happen and hey ... someone goofed up there."
