I am eigtl very pleased with the performance of this product. There is only one point who voted me a little morosely, in the assembly turned out that the little spacers are too small and the big ones too big. I own a Zotac GTX 670th Solved the problem I have as I have used a spacer.
I think that the Twin Turbo is a better alternative, since the heat sink of the Zotac already are very flat, the conversion of this would be less complicated than with a standard GTX 670
