Nvidia have been out of the chipset market for a while now, so not sure what you're on about there (Unless you mean GPUs? In which case, it's entirely irrelevant and has no real effect on CPU performance).
I was talking about the Scorpious platform, AMD have told us that the Scorpious products are designed to be used with AMD 9-series chipset motherboards and the Radeon HD 6000 series graphics cards, so it seems natural to look at those products grouped together to test AMDs claims. That was also my point about testing with 1866mhz RAM, if people had tested the products witin the original design parameters then we could test AMD's claims fully, and that's what I want to see. Now I don't think that this will automatically then achieve the 980x beating results that we were promised back in January, but I do think it will be a more complete and comprehensive test.
