Although we tested the Core i7 and Core i5 configurations on Gigabyte's P55-UD6, our Turbo Boost, Hyper-Threading, memory performance, and Windows 7 versus Vista power measurements were all taken on Intel's DP55KG motherboard.

Remember that we ran all of our gaming analysis separately in order to fit in single- and dual-card CrossFire and SLI configurations across two resolutions and seven different titles. That story can be found right here.
