Intel Core i5-661: Clarkdale Rings The Death Knell Of Core 2

Test System And Software

Though Intel shipped us its H55-based Tom Cove board for this launch, we went with Asus' P7H57D-Evo for our test platform, as the Asus board is loaded with overclocking options. Its dual PCI Express x16 slots also proved useful for confirming that H57 does, in fact, support multi-card configurations with a Lynnfield-based CPU installed.
