We've transitioned our test platform for graphics to a Sandy Bridge-E-based Core i7-3960X overclocked to 4.2 GHz. You'll notice that, in some cases, that's still not enough processing power to let some of our more demanding two- and four-GPU configurations really stretch their legs. I also made the call to swap from an Asus motherboard to a Gigabyte platform after discovering, last year during a Z68 Express motherboard round-up, that certain settings in Asus' BIOS would alter Turbo Boost behavior in an undesirable way.
