A PC tech at memory express convinced my friend that Sandy Bridge has bandwidth issues when dealing with 3 or more cards? So he got 2 6970s instead of 3 6950s.
Is that true? I'm not reading anywhere that it is true. Plus, due to results from H, we saw the complete opposite. 3x 6970s blew away 3x 580s. It was a driver problem, not a bandwidth problem.
